2-state read receipts (sent / read) via two custom packets:
MarkConsoleRead (client->server, header 4085) sent on thread focus,
relayed by the emulator to the peer as ConsoleReadReceipt (server->
client, header 4086). Client marks own messages READ and renders
checkmarks. Live-relay only (no DB table / login batch) since the
client doesn't persist message history across sessions.
Store messages to offline friends in messenger_offline (capped inbox),
replay on login via the existing FriendChatMessageComposer with an
"offline" extraData marker, and render a "sent while offline" tag in
the client thread. No new packets; emulator + small client touch.
Bite-sized TDD plan across all three codebases for the friend-groups
feature: 4 client->server category packets (renderer composers +
Arcturus handlers), DB persistence (reusing existing
messenger_categories + messenger_friendships.category), server-
authoritative re-push via existing MessengerInit/UpdateFriend
composers, and client store actions + chip-filter UI + manager modal +
per-friend assign control + pure filter helper with tests.
The slice/rim/divider/hub colors are now read from --wheel-* CSS variables
with the current values as fallbacks, so the stock look is unchanged while a
runtime theme can recolor the wheel without rebuilding.
Runtime-loaded visual re-skin system (no client rebuild, real themes never
hit git). A theme = a folder on the server (theme.base.url) with a manifest +
CSS "pieces"; each piece is toggled from Settings > Themes (checkboxes). A
broken/404 piece auto-falls back to the default (per piece). Hotel-wide default
via ui-config theme.default (+ theme.default.pieces), per-user override in
localStorage (same pattern as the catalog style toggle).
- api/theme/ThemeManager: fetch index/manifest + inject/remove <link> + fallback
- hooks/theme/useThemes: state + persist + default-from-config + live apply
- components/theme/ThemeApplier: applies on boot (mounted in MainView)
- UserSettings: General/Themes tabs with theme selector + per-piece checkboxes
- custom-themes/: reference template (demo theme "Neon Viola" + README)
- .gitignore: public/custom-themes/ (real themes are never committed)
