 - [ ] **Runtime mobile QA** — none of the above is validated on an actual phone (static analysis only). Needs device/devtools walk-through per LOTUS_TESTING §E.
 - [ ] **Element Call fork in-call mobile UI** — the EC iframe (video grid, EC control bar, spotlight) is `LotusGuild/element-call` at `/root/code/element-call` (we own it); the cinny-side audit couldn't reach it. The actual on-phone call experience is unaudited.
 - [ ] **M2 — touch discoverability** — message quick-reactions/actions are hover-gated; long-press is the fallback but is **unreliable on iOS Safari** (deep audit). A visible touch affordance is needed but the naive fix hides unread badges / clutters messages (member-profile-style redesign).
-- [~] **Sub-44px touch-target sweep** — primary controls DONE via a shared `MobileTouchTarget` `@media` class (`P1`, `8a1168bc`): in-call bar ×7, call-status bar ×4, thread "N replies" chip, knock Approve/Deny, ACL remove. **Still open:** media close/download/mute, PiP fullscreen/resize handles, read-receipt pill, presence dot (secondary).
+- [~] **Sub-44px touch-target sweep** — primary controls DONE via a shared `MobileTouchTarget` `@media` class (`P1`, `8a1168bc`): in-call bar ×7, call-status bar ×4, thread "N replies" chip, knock Approve/Deny, ACL remove. Secondary batch DONE (`r2`, `72e7447d`): image-viewer close/zoom±/zoom%/download, embed-player Close/Collapse/Fullscreen/View-post, read-receipt "seen by" pill. **Deferred (rationale, not built):** PiP fullscreen/resize handles — enlarging four 24px corners to 44px would swallow a ~160px mobile PiP and block "Return to call" (needs a design rethink, not a blunt bump); presence dot is a non-interactive status indicator (no target needed).
 - [x] **Avatar-decoration `prefers-reduced-motion`** — DONE (`P2`, `c3e1fbff`): renders just the avatar (no animated APNG overlay) under the preference; no static-frame asset to freeze to.
-- [ ] **Twitch/Twitter/TikTok preview cards** — header renders beside content on narrow (fragment into a flex-row); wrap in `Box direction="Column"` — **needs visual verify (desktop-shared)**; safest as a mobile-only `@media flex-direction:column`.
+- [x] **Twitch/Twitter/TikTok preview cards** — DONE (`r2`, `72e7447d`). These fragment cards render header/thumbnail beside content as direct children of the `UrlPreview` flex row; added `StackOnMobile` (mobile-only `@media (max-width:750px){ flex-direction:column }`) scoped to those variants via `cardClass`. folds `Box` has no default `direction` so the override wins uncontested; desktop unchanged (verified by 2 review agents). Pre-existing desktop quirk (header bar beside content on Twitter/TikTok at desktop width) left as-is — the fuller fix is wrapping each card body in a column `Box`; out of scope for a mobile pass.
 - [ ] **M2 — message action/quick-reaction touch discoverability** — hover-gated + iOS-long-press-unreliable; a visible touch affordance collides with unread-badge placement / per-message clutter → needs a design decision + device look.
