 ### 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.
+- **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. E2EE fix: the "Original" entry now uses `getClearContent()` (bypasses the replacing-event chain, returns the decrypted pre-edit body) instead of `event.content` which is still raw ciphertext for encrypted messages — fixes "(no text)" shown for almost all E2EE message originals.
 - **Inline GIF preview**: Giphy and Tenor share links sent as plain text auto-embed as animated GIFs inline in the timeline. URL patterns are detected client-side; the image is fetched via the homeserver's `/_matrix/media/v3/preview_url` proxy (no direct contact with Giphy/Tenor from the client). Rendered as `<img loading="lazy">` — respects the existing URL preview enabled/disabled setting.
 - **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.

 - **Discord-style presence selector**: Clicking your avatar in the bottom-left sidebar opens a popout with five status options — Online (green), Idle (yellow), Do Not Disturb (red, broadcasts `unavailable` with `status_msg: 'dnd'`), Invisible (grey outline, broadcasts `offline`), and Auto (activity-tracking, the original behaviour). The selected status persists across reloads via the settings atom. A colored badge on the avatar reflects the current status at a glance. `usePresenceUpdater` short-circuits immediately for manual modes; full idle-timer and visibility-change logic only runs in Auto mode. Settings also exposed via `src/app/state/settings.ts` (`presenceStatus` field).
 - **Custom status message**: Set a short status text (up to 64 characters) with an emoji picker, shown below your display name in member lists and presence displays. Accessible via Settings → Account → Profile. Includes an **auto-clear timer** (options: 30 minutes, 1 hour, 4 hours, 1 day, 3 days, 7 days) — after the timer expires, the status is automatically cleared by setting `status_msg: ''` via `mx.setPresence`. A character counter (shown when ≥ 56/64 chars) prevents overflow. Implemented in `src/app/features/settings/account/Profile.tsx`.
 - **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`).
-- **Presence avatar border ring**: A 2px colored `box-shadow` ring on user avatars throughout the app shows presence at a glance — green (online), yellow (idle), red (DND), no ring (offline). Implemented as `PresenceRingAvatar` wrapper component (`src/app/components/presence/PresenceRingAvatar.tsx`). Applied to: message timeline sender avatars, members drawer, @mention autocomplete, and inbox notification senders.
+- **Presence avatar border ring**: A 2px colored `outline` ring on user avatars throughout the app shows presence at a glance — green (online), yellow (idle), red (DND), no ring (offline). Implemented as `PresenceRingAvatar` component (`src/app/components/presence/PresenceRingAvatar.tsx`) using `React.cloneElement` to inject `outline` + `outlineOffset` directly onto the child `Avatar` element — the ring follows the avatar's actual `border-radius` regardless of shape. Applied to: message timeline sender avatars, members drawer, @mention autocomplete, and inbox notification senders.
 - **Document title unread count**: Tab title updates to `(N) Lotus Chat` for mentions, `· Lotus Chat` for unreads, `Lotus Chat` when clear.
 - **Extended profile fields (MSC4133)**: Settings → Account → Profile includes Pronouns (`m.pronouns`) and Timezone (`m.tz`) fields, saved via MSC4133 `PUT /_matrix/client/unstable/uk.tcpip.msc4133/{userId}/{field}`. Both fields are displayed in user profile panels. Implemented via `src/app/hooks/useExtendedProfile.ts`.
 - **User local time in profile**: When a user has `m.tz` set, their profile panel shows a clock icon, their current local time, and the timezone abbreviation (e.g. EST, JST). Updates every 60 seconds. Respects the viewer's `hour24Clock` setting. Implemented via `src/app/hooks/useLocalTime.ts`.

 ### UX & Composer
 
 - **Message length counter**: A muted character counter appears just left of the send button while typing, disappearing when the composer is empty. Resets on room switch.
-- **Quick emoji reactions on hover**: The 5 most-recently-used emoji reactions appear directly in the message hover toolbar (between the emoji-board button and Reply), so reacting requires a single click rather than opening the 3-dots menu first. Clicking a quick-reaction also closes any open emoji picker. Powered by `useRecentEmoji` sourced from Matrix account data.
+- **Quick emoji reactions on hover**: The 3 most-recently-used emoji reactions appear directly in the message hover toolbar (between the emoji-board button and Reply), so reacting requires a single click rather than opening the 3-dots menu first. Clicking a quick-reaction also closes any open emoji picker. Powered by `useRecentEmoji` sourced from Matrix account data.
 - **In-app notification toasts**: When a message or invite notification fires and the browser window is focused, a slim TDS-styled toast card slides in from the bottom-right instead of triggering an OS notification. Card shows: 24px avatar (initials fallback), sender name in orange, truncated message body, room name, × dismiss, 4 s auto-dismiss. Clicking navigates directly to the correct room (DM or home path) or the invites inbox. OS notifications are unchanged when the window is not focused. Implemented in `src/app/features/toast/LotusToastContainer.tsx` + `src/app/state/toast.ts`.
 - **Collapsible long messages**: Messages exceeding ~20 lines are auto-collapsed with a "Read more ↓" button. Click to expand inline; a "Collapse ↑" button re-folds. Threshold (in lines) configurable in Settings → Appearance. Uses CSS `max-height` + `overflow: hidden` — works correctly with code blocks and embedded media. Respects `prefers-reduced-motion`.
 - **Message send animation**: Own sent messages fade and scale into the timeline (0.15 s ease-out: `scale(0.97)→scale(1)`, `opacity 0.4→1`). Incoming messages are unaffected. Respects `prefers-reduced-motion`.
