    **If not:** Detect Giphy/Tenor URL patterns in the URL preview renderer and fetch the GIF via the homeserver's `/_matrix/media/v3/preview_url` proxy. If the proxy returns a direct media URL, render it as an `<img>` tag with `loading="lazy"`.  
    **Complexity:** Low-Medium (after audit).
 
+**COMPLETED June 2026.** Giphy and Tenor share URLs are detected by pattern matching in the URL preview renderer. Matching links bypass the generic OG-card layout and render directly as an `<img loading="lazy">` tag, so animated GIFs play inline in the message timeline. Fetched via the homeserver's `/_matrix/media/v3/preview_url` proxy — no direct Giphy/Tenor origin contact from the client. Respects the existing URL preview enabled/disabled setting.

   **[AUDIT REQUIRED]** — Understand how Draupnir reads policy lists on this homeserver. Confirm whether a client-side subscription UI would conflict with or duplicate Draupnir's configuration. May be more useful as a read-only viewer than a write UI.  
   **Complexity:** High.
 
+**COMPLETED June 2026.** "Policy Lists" tab added to Room/Space Settings (visible to admins only, gated by power level). Reads all rooms the local user has joined whose `m.room.create` type or name matches the policy list convention (`m.policy.rule.*`). Displays subscribed list rooms with their contents: banned users (`m.policy.rule.user`), banned rooms (`m.policy.rule.room`), and banned servers (`m.policy.rule.server`), each showing the entity, reason, and recommendation field. Subscribe (join the policy room) and Unsubscribe (leave) actions provided. Read-only viewer — Draupnir remains solely responsible for enforcement.

 **What:** Messages >~20 lines auto-collapsed with "Read more ↓" button. Click to expand inline. Collapse threshold configurable in settings.  
 **[AUDIT REQUIRED]** Determine whether CSS `max-height` + `overflow:hidden` or a line-count approach is more appropriate for the current message renderer. Check edge cases with code blocks and media embeds.  
 **Complexity:** Medium.
 
+**COMPLETED June 2026.** CSS `max-height` + `overflow: hidden` approach used on the message body container — avoids costly DOM line-count measurement and works correctly with code blocks and embedded media. Default threshold: 20 lines (~320px). A "Read more ↓" button fades in at the bottom when the message is clamped; clicking it expands inline and replaces the button with "Collapse ↑". Threshold (in lines) is configurable via Settings → Appearance. Respects `prefers-reduced-motion` — the expand/collapse transition is disabled when the media query matches.

 **Complexity:** Low.
 
+**COMPLETED June 2026.** CSS keyframe `@keyframes msgSendIn` (`scale(0.97) opacity(0.4)` → `scale(1) opacity(1)`, 0.15s ease-out) defined in `Animations.css.ts`. Applied via a vanilla-extract `style` to own-message containers (`EventStatus !== null` — i.e. local-echo messages that have not yet received a server timestamp). Incoming messages and server-confirmed events are unaffected. `@media (prefers-reduced-motion: reduce)` block sets `animation: none`.

 **[AUDIT REQUIRED]** Audit current right-click menu to avoid duplicating existing actions.

+**COMPLETED June 2026.** `RoomNavItem.tsx` context menu expanded. **Mute** item replaced with a duration submenu (via nested `PopOut`): 15 min / 1 hr / 8 hr / 24 hr / Indefinite — each calls `mx.setRoomTag(roomId, 'm.push.mute', { ...})` / push rule disable with a matching `setTimeout` to auto-restore after the selected duration (stored in `localStorage` for persistence across reloads). **Copy Room Link** copies the `matrix.to` URL to clipboard with a "Copied!" flash. **Mark as Read** calls `mx.setRoomReadMarkers()` to the latest event. **Leave Room** opens the existing leave-room confirmation dialog. **Room Settings** navigates to the room settings panel. Existing items (Rename for me, Favorites, local-name pencil) preserved.
