is_private was previously only settable at room creation. RoomUpdate now
accepts it, update_room() applies it, and PATCH /api/rooms/{id} allows a
site admin to make the change even for a room they haven't joined (in
addition to the existing room owner/admin gate) -- require_room_role
normally 403s a non-member before the role check ever runs, so this is a
deliberate bypass for site admins specifically.
Flipping the flag has no effect on existing members either direction
(confirmed is_private is only ever checked at self-serve join time) --
it purely controls Browse Rooms visibility and future self-joins.
Frontend: RoomInfoPanel's "Room settings" section is now visible to room
owner, room admin, or site admin (was owner-only), with a privacy toggle
reusing NewRoomModal's existing toggle-switch UI. "Delete room" stays
owner-only, now nested inside that wider section rather than gating the
whole thing.

A URL that points straight at an image file (Content-Type: image/*) has
no HTML to scrape Open Graph tags from, so the fetch found nothing and
the message showed no preview at all -- reported against
https://imgs.xkcd.com/comics/creepy.png.
link_preview_service now recognizes an allowed image content-type (same
list storage.py uses for uploads) before falling through to the HTML/og:
path, and returns the URL itself as the preview (LinkPreview.is_image).
No need to download the body -- the already-SSRF-validated URL is the
image. The frontend renders that case as a real expandable image
(message-image + lightbox, same as an actual attachment) instead of the
small title+description card, which would have nothing to show anyway.
Verified end-to-end against the reported URL.

Slack/Discord-style link unfurling: the first http(s) URL in a message's
content gets a small preview card (title/description/image/site name)
fetched from the page's Open Graph tags.
Backend:
- Message.preview_url (extracted at create/edit time, cheap regex, no
I/O) points at a link_previews cache row keyed by URL -- the same URL
posted in different messages/rooms fetches once, and a failed fetch is
cached too so a dead URL isn't retried on every reference.
- The actual fetch runs in a background asyncio.create_task from
broadcast_new_message/broadcast_message_update, on its own DB session,
so a slow third-party site never delays message delivery. A separate
"link_preview" WS envelope carries the result once it resolves.
- SSRF protection reuses app/services/ssrf.py's validate_target_url
(renamed from UnsafeWebhookUrlError to UnsafeUrlError now that it's
shared with webhooks), but re-validates before every hop of a redirect
chain rather than once up front -- redirects are followed manually so
each intermediate URL is checked before it's ever connected to.
- Parsed with stdlib html.parser -- no new dependency.
Frontend: a LinkPreviewCard rendered under message content when present,
patched into state live via the new WS envelope and included in message
history for reloads.

Both were thin/stale for what the project has actually grown into (the
frontend README still framed things as "Phase 1-6" and listed maybe a
third of the current src/ tree). Added a Features section and tech-stack
summary to the root README, and refreshed the frontend README's layout
listing to match what's actually in src/ today.

Every top-level page independently hardcoded a full-viewport height
(.chat-shell: 100vh, .admin-page: 100%, .login-screen family: min-height
100vh), assuming it alone owned the whole viewport. UpdateBanner renders
globally above all of them (App.tsx), so its height just stacked on top
instead of the page shrinking to make room -- on ChatShellPage specifically
(overflow: hidden), that clipped the bottom of the screen and hid the
composer behind the visible edge.
Made #root a flex column shared by the banner and whichever page is
routed, with each page now using flex: 1; min-height: 0 to fill whatever
space is actually left instead of assuming the full viewport.

Root cause, confirmed live against Postgres and reproduced end-to-end
through two real WebSocket connections: ws/chat.py shares one AsyncSession
for a whole connection's lifetime. A read-only action (e.g. a "join"
frame's membership check) can leave a transaction open with nothing to
commit it until the next write. Postgres's now()/CURRENT_TIMESTAMP
returns that transaction's *start* time in that case, not the actual
statement's -- so a reply sent after any idle/reading period got
timestamped to when the idle period started, sorting it before messages
that were genuinely sent earlier. This is independent of the two earlier
#45 fixes (missing ORDER BY tiebreakers, a stale-response race on
reload) -- both were real bugs, but this was the actual mechanism behind
"my message appears before theirs even though theirs was sent first."
Switched Message.created_at and MessageReaction.created_at from
func.now() to func.clock_timestamp(), which always reflects the actual
moment of execution regardless of how long the transaction has been
open. Migration is a plain column-default change -- no table rewrite, no
lock risk, round-trips cleanly.

The spacing scale (tokens.css) jumps from --sp-4 (1rem) to --sp-6
(1.5rem) -- there's no --sp-5. Three places referenced it anyway, so
those margin declarations were invalid at compute time and silently
resolved to 0:
- ThemeBuilderModal.css's .custom-theme-preview margin-bottom -- the bug
the user actually noticed, as a ~0px gap between the preview mockup and
the color fields below it that read as a visual overlap.
- Modal.css's .modal-divider -- a shorthand `margin: var(--sp-5) 0
var(--sp-4)`, where one invalid value invalidates the whole
declaration, so every <hr class="modal-divider"> (ProfileModal's
section separators, etc.) has had zero margin on both sides.
- AdminPage.css's .admin-invite-list margin-bottom.
All three now use --sp-6, matching the spacing tier that was clearly
intended.

Splitting the builder into a preview column and a fields column still
capped the mockup at half the dialog's width. Give it the full width of
the modal instead (name field on top, preview below spanning the whole
dialog, fields and the native-controls toggle underneath), and scale up
CustomThemePreview's own fixed pixel dimensions (~1.4x: avatar, sidebar,
paddings, font sizes) so the extra room reads as a genuinely bigger
mockup rather than the same small one with more empty space around it.
Modal width bumped from 820px to 960px to match.

The theme editor used to expand inline inside ProfileModal, whose .modal
is capped at min(380px, 100%) -- too narrow to comfortably see the live
CustomThemePreview mockup it's built around. Pulled the editor out into
a new ThemeBuilderModal (min(820px, 95vw), two-column layout above 680px)
opened on top of the profile modal, same stacked-dialog pattern already
used by ImageLightbox/FilePreviewModal. No changes to the theme data
model, activation, save, or delete behavior.

refreshHistory() fires twice in quick succession on a fresh load -- once
on mount, again when the WS 'joined' envelope arrives shortly after (for
the #37 rejoin-resync case) -- with nothing preventing a slower/stale
response (e.g. the service worker's NetworkFirst cache falling back on a
delayed request) from resolving last and overwriting a newer, correct
one. Track the latest-initiated request and drop any response that isn't
from it.
Confirmed via a production DB check that there are no duplicate
created_at timestamps, ruling out the timestamp-precision theory -- the
actual scrambling was two competing fetches racing, not a data problem.

A backend restart during a deploy kills every open WebSocket, and the
chat socket's existing reconnect-with-backoff already re-fires onopen
within seconds -- reuse that as a reliable "the server just restarted"
signal to check for a new service worker version, instead of waiting up
to an hour for UpdateBanner's poll. The hourly poll stays as a fallback.

The 12 color pickers (Background, Sidebar background, Surface, Border,
etc.) gave no indication of what each one actually affects without
trial and error. Adds a miniature, self-contained mockup of the real
chat UI above the picker grid -- a sidebar with room rows, a message
with an avatar/mention/role badge, a composer, a danger button -- styled
from inline styles bound to the draft colors (not the --ds-* custom
properties, since those reflect whatever theme is currently active, not
necessarily the one being edited).
Hovering or focusing either a color input or its matching element in
the mockup highlights both, using a fixed amber outline that stays
visible regardless of the theme's own palette -- makes the mapping
between the 12 fields and where they actually show up immediately
obvious in either direction, without needing to activate the theme and
go look around the rest of the app.

Two independent gaps, both fixed since the report was ambiguous about
which "chats" meant:
- ChatPane.tsx concatenated history (REST-fetched) and live (WS-pushed)
without sorting, so anything that could desync receipt order from
send order -- a rejoin/resync racing a still-in-flight WS message,
which opening the same room on another device triggers directly via
a fresh socket connection -- could render messages out of
chronological order. Now sorted by created_at (stable sort, so
same-timestamp messages keep their relative order).
- list_member_rooms/list_open_rooms/list_recent_messages ordered by
created_at alone, with no secondary tiebreaker. Postgres doesn't
guarantee a stable order for tied rows across separate query
executions, so two rooms/messages sharing an identical timestamp
(a real possibility -- rapid sends, bulk-created rooms) could come
back in a different order on two separate fetches, i.e. two devices.
Added id as a secondary sort key everywhere this showed up.

MessageImage has no stored original filename, so this relies on a bare
`download` attribute (no explicit filename) rather than adding
filename support server-side to match the file-attachment pattern --
the image-serving response's existing Content-Type header is already
enough for the browser to infer a sensible extension on its own.
RoomInfoPanel's Files section reuses the same shared ImageLightbox
component, so its image rows get the same download button for free
with no separate change needed there.

Both account-creation surfaces now require the password twice:
- Web signup (invite-based self-service): SignupComplete gains a
password_confirm field with a model_validator backstop server-side,
plus a client-side match check in SignupPage.tsx for immediate
feedback -- the client check is the primary UX, the server check is
defense in depth so the guarantee doesn't rely on the client alone.
- CLI (python -m app.cli create-user): password is now an optional
positional argument. If omitted, prompts interactively via getpass
(hidden input) twice, retrying on mismatch -- matching what "entered
twice and verified" actually means for a human typing blind. Passing
the password directly as before still works unchanged, for scripted/
automated provisioning.

Reuses the existing upload path unchanged: handleFileSelected's body is
now handleFile(file), called from both the file-input's onChange and a
new onDrop handler on the composer, so drag-and-drop and the "Attach a
file" button share the exact same size-check/branch-on-content-type/
error-surfacing logic rather than duplicating it.
Only the first dropped file, matching the existing single-attachment-
per-message limit. A dashed-border overlay appears while dragging over
the composer for discoverability; a nested dragenter/dragleave counter
keeps it from flickering as the drag crosses child element boundaries.

@username tokens in a sent message are parsed against the room's actual
members (skipping fenced/inline code, so pasted code isn't misread) and
recorded as MessageMention rows, reusing #38's read-tracking and
offline-member broadcast infrastructure rather than building a parallel
notification path:
- Sidebar: a mentioned-and-unread room shows a distinct highlight-
colored badge instead of (not alongside) the plain unread dot --
computed the same way as has_unread, just scoped to messages that
mention the caller, and cleared by the same last_read_at mark-read
flow.
- Push notifications: a mentioned offline recipient gets "X mentioned
you: ..." instead of the generic "X: ...", still per-recipient since
the same message can page some room members and not others.
- Message rendering: a validated @username is highlighted inline,
implemented by turning it into a `[@username](mention:username)` link
before markdown parsing and overriding link rendering to style
`mention:`-scheme links as a span instead of an anchor -- reuses
markdown-to-jsx's existing parser rather than hand-rolling text-node
splitting.
- Composer: typing @ opens an autocomplete dropdown of matching room
members (arrow keys to navigate, Enter/Tab/click to insert, Escape or
moving the cursor away to dismiss).

Replaces the single custom_theme_colors blob (one palette per user) with
a proper CustomTheme table -- users can now save, name, and switch
between as many custom palettes as they like, not just one.
Data model: users.active_custom_theme_id references whichever saved
CustomTheme (if any) is currently active; theme='custom' + that id
together determine what's rendered. The migration data-migrates any
already-saved single palette into a named CustomTheme row on upgrade,
and best-effort backfills the active one back into the old column shape
on downgrade.
New endpoints under /api/custom-themes: list, create, rename/recolor,
delete (falls back the user to a preset if the deleted theme was
active, so the two theme columns can never disagree), and activate.
UserRead.active_custom_theme is only populated when theme == 'custom'
even though the DB deliberately keeps the id set while a preset is
active, so switching to a preset and back doesn't lose the saved
palette.
ProfileModal now lists saved themes as swatches (click to activate,
pencil to edit -- active or not, trash to delete with a confirm), plus
a "+ New" button that creates, activates, and opens the editor for a
fresh theme immediately.

Extends the existing fetch-and-bypass-Content-Disposition pattern
already used for text/markdown previews: the PDF's bytes are fetched
into a Blob and handed to the browser's native viewer via a blob: URL,
which carries no HTTP headers of its own. That sidesteps
Content-Disposition: attachment the same way a script-initiated fetch()
already does for text, without needing an <iframe>/<embed> to navigate
to the real file URL directly (which would respect that header and
force a download) -- and without the backend allowlist endpoint this
issue's original scoping assumed would be necessary.
MIME type is forced to application/pdf explicitly rather than trusted
from the upload, since getPreviewKind gates on the .pdf extension alone
(matching its existing behavior for .md/.txt), so a mislabeled file
still renders instead of downloading or erroring. Object URLs are
revoked on unmount/file-change to avoid leaking memory.

Adds a 5th "Custom" option to the theme swatch grid alongside the
existing 4 presets, opening a picker for all ~12 CSS custom properties
(backgrounds, borders, text, three accent tiers, highlight, danger) plus
a light/dark toggle for native control rendering.
Persisted as a new users.custom_theme_colors JSONB column, validated
server-side against exactly what a native <input type="color"> can ever
produce. Colors survive switching to a preset and back, since there's no
reason picking a preset for a moment should force redoing every color
pick. Applied at runtime as inline custom properties on :root (presets
stay static CSS) via a shared applyTheme() helper, which is also
responsible for clearing those inline overrides when switching away --
otherwise they'd silently keep winning over whatever preset's own
stylesheet values should apply next.
Live preview on every color change; persists only on explicit "Save
colors" (not per keystroke, since a color input fires continuously while
dragging), and closing the modal without saving reverts the preview back
to whatever's actually persisted.

Shows a dot on rooms with unread messages in the sidebar, updated live
over WebSocket. Reuses the same offline-member audience computation
already used for push notifications: a member gets the real-time signal
whenever they aren't currently connected to that room's channel, which
correctly covers both "room not open" and "room open but tab
backgrounded" (the client leaves a room's channel while hidden).
Persisted server-side via a new room_memberships.last_read_at column so
state survives reload and stays consistent across devices, advanced by
an explicit mark-read call the frontend makes on room-open and on each
live message received while the room is genuinely visible -- gated on a
live visibility check, not a cached ref, so a backgrounded-but-open room
keeps accumulating unread instead of auto-marking-read the instant a
message arrives somewhere it can't be seen.

logout() cleared the session but never called unsubscribeFromPush(),
so a browser's push subscription (and its server-side row) outlived the
session indefinitely -- the logged-out account kept silently receiving
pushes for as long as that browser stayed open. Runs before the session
cookie is cleared since the unsubscribe call is authenticated, and is
best-effort so a failure there can't block logout itself.

Shows up to 8 most-recently-picked emoji, pinned above the regular
categories, whenever the picker isn't in search mode -- shared by both
the composer's insert-emoji button and message reactions, since both
go through the same EmojiPicker component. Stored in localStorage
(frontend/src/lib/recentEmoji.ts), per-browser rather than synced
across devices, matching this app's existing local-only preferences
(e.g. the resizable-panel widths).
Verified in-browser: no section when empty, a pick is recorded and
shows up on reopen, order is most-recent-first, re-picking an already-
recent emoji moves it to the front without duplicating, and the list
caps at 8 by dropping the oldest entry.

Root cause of "still not getting push notifications while backgrounded"
despite #31: joinRoom() was made to send unconditionally on the theory
that opening a room always implies genuine visibility (a real click
can't happen on a truly hidden tab). That's wrong for one real case --
mobile Chrome can silently discard and later reload a long-backgrounded
tab from memory, which re-mounts the room and calls joinRoom() again
with nobody actually looking at the screen. Each such reload re-joined
the room's presence with no matching "leave" (a discard skips normal
unmount cleanup), so a room could accumulate a stuck presence entry
that permanently suppressed push notifications for it -- confirmed
live via a user's server logs (repeated silent WS reconnects, and
their account still showing present in the room's Redis presence hash
while genuinely backgrounded).
joinRoom() and the reconnect replay now check document.visibilityState
live instead of trusting a cached ref or sending unconditionally: a
still-hidden reload correctly stays "left" (the room stays in
desiredRoomsRef, so the next genuine foreground transition still joins
it, just deferred instead of wrongly immediate), while a real
user-driven open still joins immediately as before.
Verified both directions in the browser: mounting a room while
genuinely hidden leaves the room's presence hash empty; a subsequent
real visibility transition to visible correctly triggers the deferred
join.
Note: this prevents new stuck entries but doesn't retroactively clear
any that already exist -- an affected user needs one real close
(not just backgrounding) to send a clean disconnect and reset the
stuck refcount.

The WebSocket connection lived entirely inside ChatShellPage, so
navigating to /admin (which never opens its own connection) unmounted
it -- the server correctly marked the user offline since the
connection genuinely closed, even though they were still logged in
and using the app. New ChatSocketContext.tsx hoists the connection to
App.tsx, shared across every authenticated route via a single
provider (keyed by user id, so a logout/login as a different account
gets a clean reconnect rather than an old connection lingering under
a new identity) instead of living inside whichever page happens to be
mounted.
Verifying that fix surfaced a second, independent bug: #31's
visibility handling had gated the *explicit* joinRoom/leaveRoom calls
(fired when a room actually mounts/unmounts in the UI) on the same
isVisibleRef check meant for automatic background/foreground
transitions. That's wrong -- a room can only be opened by a real user
interaction, which can't happen on a genuinely backgrounded tab, so
gating it too meant a stale or momentarily-wrong visibility reading
at mount time could silently skip the join with nothing to ever retry
it. joinRoom/leaveRoom now always send immediately; only the
automatic hide/show transitions and the reconnect replay stay gated
on visibility, which is what #31 actually needed.
Verified both end-to-end in the browser: navigating to /admin via
real in-app navigation (not a reload) keeps the presence dot online,
confirmed via direct Redis inspection and the /api/users/online
endpoint; opening a room and sending a message works immediately
afterward.

The service worker already auto-updates in the background (registerType:
'autoUpdate' + an unconditional self.skipWaiting()), but that just
silently swaps the SW -- nothing ever told an already-open tab its
already-loaded JS had fallen behind, so a long-lived tab could run a
stale build indefinitely.
Switched registerType to 'prompt': a new SW now installs and waits
rather than taking over immediately, activating only when the page
explicitly asks (sw.ts's skipWaiting is now conditional on a
SKIP_WAITING message instead of unconditional). UpdateBanner.tsx uses
vite-plugin-pwa's virtual:pwa-register/react hook to surface that as a
small banner with a Reload button, and polls for updates hourly so a
tab that never navigates still notices eventually.
Verified a fresh install shows no banner (correct baseline) and the
code follows the documented registerType: 'prompt' pattern exactly.
Could not get this sandbox's browser to actually detect a swapped
service-worker file via registration.update() during testing --
confirmed via direct inspection that the server serves the new
content correctly and ruled out timing, so this looks like an
update-check limitation specific to this automated browser
environment rather than a bug; the real test is the next live deploy.
Also adds a "frontend-preview" launch.json entry (npm run preview) --
the only way to exercise the real production service worker locally,
same reasoning as vite.config.ts's existing `preview.proxy` section.

Root cause (found earlier): the server only pushes to users it
believes are "connected" to a room, but that was a raw WebSocket-
connection check with no concept of whether the tab was actually
foregrounded -- a backgrounded-but-still-connected tab looked exactly
like someone actively watching, so the push got suppressed even
though nothing could surface on a hidden page.
No backend change needed: the server's presence tracking (and the
push-suppression logic built on it) was already correct for "not
joined to this room's channel" -- the gap was purely that the client
never told it about backgrounding. useChatSocket.ts now tracks
document.visibilityState and sends "leave" for every desired room
when hidden (without forgetting the app still wants them joined), and
"join" again when visible -- reusing the exact join/leave path a real
room switch already goes through, no new WS message type or backend
logic required.
Rejoining also triggers a message-history refetch in ChatPane (keyed
off the server's existing "joined" ack), so anything sent while
backgrounded gets backfilled instead of silently missing -- as a side
effect, this also fixes reconnect-after-a-dropped-connection never
backfilling either, which had the same gap.
Verified end-to-end: simulated backgrounding in the browser and
confirmed via direct Redis inspection that the room's presence hash
(what push-suppression actually reads) goes empty on hide and
repopulates with a message resync on show.

Every avatar in the app (chat messages, room member list, your own
avatar in the top bar/profile, the admin user list, the room-invite
search) now shows a green/red presence dot. Also adds a global
"Appear offline" toggle in the account menu, letting a user lurk in a
room undetected -- it overrides the real connection state everywhere,
not per-room.
Backend: new GlobalPresence (backend/app/ws/global_presence.py), a
cross-instance Redis-backed connection tracker parallel to the
existing per-room Presence, incremented/decremented on WS connect/
disconnect. A new users.appear_offline column (migration
f0f6e494454a) always wins over actual connection state when computing
displayed status. RoomMemberRead gained a computed `status` field;
add_member/change_member_role/list_room_members all compute it via a
shared _member_status() helper. Connect/disconnect and profile
updates (display_name, avatar, appear_offline) all broadcast
member_updated to every room the user belongs to, reusing the
broadcast infrastructure from the earlier avatar-staleness fix, so
chat surfaces update live with no new WS envelope type needed. A new
GET /api/users/online gives the admin list and user-search a snapshot
(deliberately not live -- see backend/app/routers/users.py) for
surfaces where "accurate as of page load" is good enough.
Frontend: UserAvatar renders an optional status dot; every call site
threads status/appear_offline through from whichever data source it
already has (room members, the current user, or the new online-ids
snapshot for admin/search).
4 new backend tests (backend/tests/test_presence.py); existing
broadcast-adjacent WS tests updated to tolerate the new member_updated
noise on connect. Verified end-to-end in the browser with two real
users: presence dot flips live on connect/disconnect via the existing
room-broadcast channel, and the lurk toggle correctly forces offline
while still connected.

The service worker cached /api/rooms/mine, /api/rooms, .../messages,
.../members, and /api/invites/mine with StaleWhileRevalidate: serve
the previous cached response immediately, refresh the cache in the
background for next time. That means every repeat visit showed
content one visit behind -- reopening a room after someone messaged
it, or checking a second device, both showed stale data until a
manual reload (which finally picked up the now-revalidated cache).
Only registers in a production build (vite dev never activates it),
which is why this didn't surface during in-browser testing this
session for #26/#27/#34.
Switched all five routes to NetworkFirst: always prefer a live
response, fall back to cache only when the network request itself
fails or times out (genuinely offline), keeping the "readable while
offline" behavior without the staleness.
Verified against a real production build (`vite preview`, the only
way the SW actually registers): sent a message from a second session
against an already-cached room, and the very next fetch showed it
immediately with no staleness.

Browsers already spellcheck a plain <textarea> by default (confirmed
in-browser: spellcheck read true on the composer with nothing
disabling it), but that's an implicit default rather than a guarantee

Another user's new display name or avatar didn't show up until you
reloaded -- update_profile/upload_avatar/remove_avatar never told
anyone. Same root cause and fix shape as #26 (room_added): the
frontend's already-fetched member list had no way to hear about a
change, since nothing ever pushed one.
Reuses the existing per-room broadcast channel (not the per-user one
#26 added, since this only matters for rooms the affected user shares
with someone currently looking at them) -- publishes member_updated to
every room the user belongs to; ChatShellPage refetches members when
it arrives for the currently open room.
Verified end-to-end in the browser: one user's room-info member list
updated live when another user changed their display name from a
separate session, no reload.

Reacting to a message near the bottom of the scrolled list opened a
picker that ran off-screen and couldn't be used -- placement was
hardcoded to "below" regardless of the trigger's actual position.

raw :name: text, same as markdown itself is never converted until
display. Fenced code blocks and inline code spans are skipped so
pasted code (a Ruby symbol, a dict key) isn't silently mangled.
frontend/src/lib/emojiShortcodes.ts is generated once from
emojibase-data's GitHub shortcode set (same one-time-generator approach
as #19's emojiNames.ts, never a runtime dependency) -- 928 of the
app's 936 emoji matched, 956 aliases, no collisions.

Previously GET /api/rooms/mine was only ever fetched once at app mount,
so a room added mid-session stayed invisible until a full page reload
-- add_member had no way to reach an already-open client at all.
Backend: ConnectionManager and Broadcaster (renamed from RoomBroadcaster)
now support per-user channels alongside the existing per-room ones, so a
signal can reach a user's socket even for a room they haven't joined
(and by definition can't have, until this fires). add_member publishes
a room_added event on the target user's channel.
Frontend: the WebSocket connection is no longer scoped to whichever
room is open -- ChatShellPage now owns one persistent connection for
the whole session (including while no room is open, which is exactly
when this bug showed), and ChatPane joins/leaves rooms on top of it.
A room_added event triggers a room-list refetch with no reload needed.
Verified end-to-end in the browser: a user sitting on the empty room
list saw a newly-added room appear live, then chatted in it normally.

The composer's message textarea lacked min-width: 0, so on browsers
that compute a larger default intrinsic width for flex-child form
controls (observed on Firefox for Android), the row could overflow
and push the fixed-width send button past the viewport edge instead
of shrinking the textarea to fit.

RoomInfoPanel was hard-gated behind !isMobile in ChatShellPage.tsx, but
its trigger button ("Room details" in ChatPane.tsx) still rendered and
toggled state unconditionally -- tapping it on mobile did nothing
visible, with no way to reach room info/members/settings at all. Fixed
by removing the gate and making the panel itself responsive: it renders
as a full-screen fixed overlay below the mobile breakpoint instead of
the desktop resizable aside (which stays exactly as before -- verified
in-browser at both viewport sizes).
Also found and fixed a second real bug during the mobile audit: the
emoji picker's fixed 320px width overflows a 375px-wide viewport by 5px
depending on trigger position (e.g. the composer's emoji button, near
the left edge). Shrunk it to 280px with a proportionally reduced column
count below 480px, rather than attempting dynamic position-aware sizing
for a 5px overflow.

A search box in EmojiPicker filters the flat emoji list by name/keyword
instead of only browsing by category, shared by both the composer's
emoji trigger and the message reaction picker.
Names/keywords didn't exist anywhere in this codebase before (emoji.ts is
just raw unicode characters). Rather than hand-typing entries for all 928
unique emoji -- a lot of manual work, and unlike the codepoints themselves
a wrong name only means a bad search result, not a broken emoji, so the
accuracy argument for hand-typing didn't apply here -- generated
emojiNames.ts once from emojibase-data (MIT licensed), matched against
emoji.ts by codepoint (normalizing variation-selector differences between
the two sources). emojibase-data itself was never added to package.json;
it was only ever a one-time generation tool, so this ships with zero new
runtime dependency.

The NOPASSWD rule from 3f only covered the bare `systemctl status
ds-chat` with no arguments, but deploy/upgrade.sh actually calls it with
`--no-pager -l`. Sudoers matches commands on the exact argument string
unless a wildcard is present, so the extra flags fell through to a
password prompt on every upgrade run -- one that can never actually be
satisfied, since ds-chat correctly has no password at all (a nologin
system account). Added a wildcarded pattern alongside the exact one so
upgrade.sh's real invocation matches.

cfg.use_tls was passed straight through as aiosmtplib's use_tls kwarg,
which means implicit TLS -- encrypted from the first byte, port 465's
convention. Port 587, what most providers (including the one that
surfaced this: DreamHost) document as their primary submission port,
needs STARTTLS instead -- a plaintext connection that upgrades in-band.
Forcing implicit TLS against a STARTTLS-only port breaks the handshake
outright: [SSL: WRONG_VERSION_NUMBER], a client TLS ClientHello sent to a
server still expecting a plaintext SMTP greeting.
The "Use TLS" checkbox still means "encrypt this connection" -- the fix
infers which of the two negotiation modes to use from the port (465 ->
implicit, everything else -> STARTTLS), matching the convention every
mail client uses. start_tls is passed as an explicit requirement rather
than left to aiosmtplib's opportunistic default, so a server that turns
out not to support STARTTLS fails loudly instead of silently sending in
plaintext despite the admin asking for encryption.

Three real, reproducible bugs in DEPLOYMENT.md's app-server setup steps,
each found by actually following the guide on a real box rather than
static review:
- useradd --system --create-home is unreliable on Debian in both
directions: sometimes it silently skips creating the home directory,
sometimes it creates it AND populates it from /etc/skel
(.bashrc/.profile/.bash_logout). Either way it broke a later step --
the skel files make git clone refuse to clone into a non-empty
directory. Fixed by dropping --create-home and creating the directory
ourselves, deferring anything else that goes in it (uploads/) until
after the clone.
- Documented a personal/deployment-user access token as a first-class
alternative to the SSH deploy key for cloning, alongside its plaintext-
in-.git/config tradeoff.
- The create-user command nested a user-chosen password inside two layers
of shell quoting (an outer bash -c '...' plus inner double quotes) --
fragile for any password with a space or a literal '. Replaced with
dropping into an authenticated interactive shell first, so there's only
one layer of quoting to get right at an actual prompt.

DEPLOYMENT.md: two spots (§7 backups, §9 known gaps) said "images" when
they should say "images and file attachments" -- generic file attachments
(#13) share the exact same no-backup-coverage and orphaned-upload gaps as
images, but the wording was never updated when that feature shipped.
ARCHITECTURE.md §9.2 and the tech-stack table described a materially
different, outdated architecture: nginx running on the app server,
reverse-proxying to gunicorn over a Unix socket. The actual setup (which
DEPLOYMENT.md already correctly documents) has no nginx on the app server
at all -- gunicorn binds a TCP port directly, and TLS/reverse-proxying is
handled by an external, pre-existing Nginx Proxy Manager instance. Rewrote
both to match reality.

Four preset color themes, switchable from Profile settings with instant
preview and server-side persistence (User.theme, applied via a data-theme
attribute the CSS custom-property overrides in themes.css key off). Dark
stays the existing DarkSingularity palette and default. Light is a genuine
new light-mode design; Midnight is a higher-contrast OLED-friendly dark
variant; Sunset swaps in a warm amber/coral accent family.
Custom theme building (pick-your-own-colors) is out of scope for this
pass -- presets only.
Also: fixed the PATCH /api/auth/me handler to only apply fields actually
present in the request body. It previously always overwrote display_name
unconditionally, which happened to be harmless when it was the only
field on ProfileUpdate but would have silently cleared it on any
theme-only update. And switched two hardcoded hex colors
(.btn-primary:hover, .role-badge-admin) to token-derived color-mix()
values so they adapt across themes instead of staying fixed to the
original cyan/violet palette.

Clicking a .md/.txt attachment now opens a modal instead of downloading,
with an explicit download button still available inside it. Markdown
renders through the same XSS-safe renderer used for chat messages;
plain text renders as literal escaped content via <pre>.
No backend change needed: the preview content is read via fetch(), which
is unaffected by the Content-Disposition: attachment header the file-serve
endpoint always sends (that header only steers the browser's own
navigation/embed rendering, not a script-initiated body read) -- so the
existing download-forcing security behavior from #13 stays intact.
Non-previewable types (PDF, etc.) are unchanged.

Renames the app's display name everywhere (page titles, PWA manifest,
TopBar, email subject lines, HMAC signature header) and its internal
technical slug from chatapp to ds-chat/ds_chat: the Python package name
and console script, the systemd unit and its user/group/paths, the deploy
scripts, the Docker container names, and the Postgres database name.
The live dev Postgres role stays "chatapp" -- renaming a role requires
disconnecting the session using it, which needed a temporary superuser
role Claude's auto-mode classifier correctly declined to create
unsupervised. Functionally invisible (it's just a login credential), but
worth knowing about if this ever needs fully cleaning up by hand.

The 8MB image/file/avatar cap is now a site setting (UploadSettings,
single-row table like SmtpSettings) editable from the Admin Settings tab,
instead of a hardcoded constant. All three upload endpoints read the live
value and interpolate it into their 413 messages. A new GET
/api/uploads/limit endpoint (open to any authenticated user, unlike the
admin-only settings endpoints) lets the composer reject an oversized file
client-side before it ever hits the network, though the server still
enforces the same cap independently.

Messages can now carry an arbitrary file (MessageFile), parallel to the
existing MessageImage feature rather than a refactor of it. Files serve
with Content-Disposition: attachment to force a download and prevent an
uploaded HTML/SVG from executing same-origin. No content-type allowlist,
same 8MB cap as images for now (a separate size-limit redesign is tracked
as its own issue).

Renders message content with markdown-to-jsx: bold/italic/strikethrough,
inline code, fenced code blocks, blockquotes, lists (incl. nested and
task lists), tables, footnotes, headings, and highlight (==text==).
Raw HTML in message content is parsed to escaped literal text rather
than rendered (disableParsingRawHTML), which is the XSS mitigation for
this being user-generated content -- verified against both <img
onerror> and <script> probes. Markdown image embeds degrade to a link
instead of an <img>, since the app already has a first-class image
upload and a second silent remote-image-embed path would duplicate it
and leak the viewer's IP to arbitrary URLs.
The inline message-edit control is upgraded from a single-line <input>
to a <textarea> so multi-line markdown can actually be edited without
losing newlines, mirroring the Composer's Enter-sends/Shift+Enter-
newlines convention.
Since CommonMark treats a single newline as a soft break (collapses to
a space) rather than a visible line break, added a small code-fence-
aware preprocessor that converts single newlines to hard breaks --
without it, existing multi-line messages sent via the Composer's
Shift+Enter would silently collapse onto one line.
Also fixes heading levels rendering at an identical capped size
(should still step down by level, just capped lower than default), and
adds CSS for markdown constructs the library already parsed but hadn't
been styled for the dark theme: table borders, highlight/mark color,
task-list checkbox accent, and footnote divider.
The old list was a small hand-picked subset that was missing common
ones (party popper, facepalm, shrug, etc.). Reorganized into ten
categories (Smileys, People & Gestures, Hearts, Animals & Nature,
Food & Drink, Travel & Places, Activities & Sports, Objects, Symbols,
Flags) with much broader coverage in each. Widened the picker panel
and bumped the grid to 9 columns to fit the larger set comfortably.
