chore: prettier formatting for P0 feature files

 - **Dark mode in element-call**: After joining, `CallEmbed.applyStyles()` injects `:root { color-scheme: dark|light }` into the iframe document so `@media (prefers-color-scheme)` rules inside element-call resolve to the correct Cinny theme regardless of the OS system preference. `themeKind` is stored on the `CallEmbed` instance and updated on every `setTheme()` call, so live theme switching also re-injects the CSS. Without this, users with OS light mode would see a white background even when Cinny is in dark mode.
 - **Call embed wallpaper**: The user's `chatBackground` pattern (Blueprint, Carbon, Stars…) is applied as the `backgroundImage`/`backgroundColor` of `div[data-call-embed-container]` when the call is in full view (not PiP). The iframe `html, body` is forced to `background: none !important` so the pattern shows through. When `chatBackground` is `none`, behaviour is unchanged.
 
+### Moderation
+
+- **Report Room**: A "Report Room" option in the room header menu (⋮) allows users to report a room to homeserver admins with a reason and abuse category (Spam / Harassment / Inappropriate Content / Other). Calls `POST /_matrix/client/v3/rooms/{roomId}/report` (MSC4151, confirmed supported on matrix.lotusguild.org). Implemented in `ReportRoomModal.tsx` with loading/success/error states.
+
 ### Messaging Enhancements
 
+- **Rich room topics**: Room topics that contain formatted text (bold, links, italic) are now rendered with full HTML formatting. Falls back to plain text if no `formatted_body` is present. Activates when any room admin sets a formatted topic.
+- **Edit history viewer**: Clicking the "edited" label on any edited message opens a modal showing every prior version with timestamps. Fetches all `m.replace` relations for the event and displays them oldest-to-newest. Previously the "edited" label was visible but unclickable.
 - **GIF picker**: Giphy-powered GIF search and send. Button appears in the message composer only when `gifApiKey` is set in `config.json`. Sends GIF as `m.image` — fetches blob, uploads via `mx.uploadContent`, sends with `mx.sendMessage`. `FocusTrap` handles click-outside / Escape to close. When TDS is active: dark navy background (`#060c14`), orange dim border, `// GIF_SEARCH` header, CSS overrides for Giphy SDK search bar (dark bg, orange border/focus ring, JetBrains Mono), custom orange scrollbar. All TDS styles live in `lotus-terminal.css.ts` — no runtime `<style>` injection, eliminating flash of unstyled content.
 - **Message forwarding**: Forward any message to any room from the message context menu.
 - **Draft persistence**: Unsent message drafts survive page reload via `localStorage` (`draft-msg-<roomId>`). Jotai in-memory atom is primary; localStorage is used as fallback on reload and cleared on send.

 - **Location sharing**: Map embed view for incoming location events + static share button. Renders `m.location` events inline with a map tile.
 - **Deleted message placeholders**: Redacted `m.room.message`, `m.room.encrypted`, and `m.sticker` events render as "This message has been deleted" with reason (if provided) rather than disappearing. One-line change in the `eventRenderer` filter in `RoomTimeline.tsx`.
 
+### Room Customization
+
+- **Personal room name overrides**: Right-click any room in the sidebar → "Rename for me…" to set a local display name visible only to you. Other members see the original name unchanged. A small pencil icon marks rooms with a custom local name. Stored in Matrix account data (`io.lotus.room_names`). Uses `io.lotus.room_names` account data key (based on MSC4431).
+
 ### Per-Message Read Receipts
 
 Full per-message read receipt system — shows who has read each message directly in the timeline.

 - **Presence badges on members**: Online/busy/away dots shown next to users in the room members drawer and settings members panel (`PresenceBadge` component from `src/app/components/presence/Presence.tsx`).
 - **Document title unread count**: Tab title updates to `(N) Lotus Chat` for mentions, `· Lotus Chat` for unreads, `Lotus Chat` when clear.
 
+### Server Integration
+
+- **Server support contact (MSC1929)**: Settings → Help & About displays the homeserver admin contact fetched from `/.well-known/matrix/support`. Shows the admin's Matrix ID and a link to the support page when the homeserver has configured this endpoint. Degrades gracefully when not configured (section is hidden on 404 or network error). In TDS mode the contact text and link render in `--lt-accent-cyan`. Implemented in `src/app/features/settings/about/About.tsx`.
+- **Server notices**: Rooms of type `m.server_notice` (system messages from the homeserver) now render with a distinct "Server Notice" `<Chip variant="Warning">` badge in the room header and a disabled composer showing "This is a server notice room — you cannot send messages here." Previously indistinguishable from regular DMs. Badge in `src/app/features/room/RoomViewHeader.tsx`; composer guard in `src/app/features/room/RoomInput.tsx`.
+
 ### Infrastructure
 
 - **Authenticated media**: All avatar/media loads use `mxcUrlToHttp(mx, mxcUrl, useAuthentication, w, h, 'crop')` from `../../utils/matrix` — the Lotus utility that handles MSC3916 authenticated media. (Upstream Cinny uses the SDK method with incorrect argument order for authenticated endpoints.)
 - **Upstream tracking**: `git remote add upstream https://github.com/cinnyapp/cinny.git`. Merge strategy: `git fetch upstream && git merge upstream/main`. Daily check via `cinny-upstream-check.sh` on LXC 106 — notifies Matrix on new upstream commits.
 - **Rolldown CJS interop — millify**: `src/app/plugins/millify.ts` uses a named import (`import { millify as millifyPlugin } from 'millify'`) instead of a default import. Rolldown's `__toESM` helper with `mode=1` sets `a.default = module_object` (not the function itself) when `hasOwnProperty` prevents the copy — calling `millifyPlugin()` would throw `(0, zc.default) is not a function`. Named import bypasses the interop entirely.
 - **Sentry noise filter**: `ignoreErrors: ['Request timed out']` added to `Sentry.init` in `src/index.tsx` to suppress unhandled rejections from the matrixRTC delayed-event heartbeat (matrix-sdk) and the widget PostmessageTransport initial-load race (matrix-widget-api). Neither is actionable from client code.
+- **URL preview default in encrypted rooms**: `encUrlPreview` default changed from `false` to `true` in `src/app/state/settings.ts`. A security note is shown next to the toggle in Settings → General explaining that the homeserver fetches the URL (and sees it) but not the message content.
