### What changed?
After a new mobile invite claim succeeds, Buzz now best-effort ensures
membership in the same public starter channels as desktop:
- `#general`
- `#welcome-everyone`
Missing starters use desktop's deterministic per-relay IDs and exact
public channel configuration, so concurrent mobile and desktop setup
converges safely. Setup failures do not invalidate or retry an already
successful invite claim, and failure for one starter does not block the
other.
The success sheet offers **Continue to #welcome-everyone** when that
channel is available. Mobile does not create the private `Welcome`
channel because it cannot provision the desktop Welcome agents that make
that channel useful.
This PR is stacked on #6145 because it deliberately reuses that PR's
open-channel directory and join behavior. Once #6145 merges, this PR can
be retargeted to `main` without changing its BUZZ-12 diff.
Fixes
[BUZZ-12](https://linear.app/squareup/issue/BUZZ-12/bug-community-appears-empty-after-using-invite-link-on-mobile).
### How is it tested?
- Desktop/mobile deterministic starter-ID parity coverage.
- Existing-channel join and missing-channel creation coverage.
- Duplicate-create convergence and per-channel failure isolation
coverage.
- Invite success remains successful when starter setup fails.
- Widget coverage for continuing directly into `#welcome-everyone`.
- Focused invite/deep-link tests: 23 passed.
- `just mobile-check`: passed.
- `just mobile-test`: 1,483 passed.
- Pre-push repository checks: passed.

**Category:** new-feature
**User Impact:** People who lose a desktop identity can securely restore
it from a signed-in Buzz phone without creating a replacement identity.
**Problem:** A fresh or identity-lost desktop could not recover its
existing full Buzz identity from an already-authorized phone.
**Solution:** Add a SAS-confirmed reverse NIP-AB transfer, durable
desktop import, a dedicated mobile recovery entry point, and clearer
desktop recovery dialogs with tested loading, drag-and-drop, and failure
states.

**Category:** new-feature
**User Impact:** Mobile now keeps each community’s appearance in sync
with desktop, including theme, accent, and system-mode preference.
**Problem:** Appearance choices were device-local, so the same account
could look different between desktop and mobile. Live sync could also
stop after the relay closed a subscription.
**Solution:** Store each community’s encrypted appearance preference on
its relay using the shared desktop wire contract, restore it from a
local identity-scoped cache, and apply replacement events live. Closed
subscriptions now recover with guarded backoff and fetch the latest
preference so no update is lost during the gap.

**mobile/lib/app.dart**
Connects community appearance state to the authenticated app lifecycle.
**mobile/lib/features/settings/accent_picker_page.dart**
Aligns mobile accent choices and selection behavior with the shared
catalog.
**mobile/lib/features/settings/settings_page/appearance_section.dart**
Clarifies the active appearance and hides accent controls when the Buzz
theme owns its neutral accent.
**mobile/lib/features/settings/theme_picker_page.dart**
Persists catalog theme choices through the community-scoped provider.
**mobile/lib/shared/theme/accent_colors.dart**
Matches desktop’s accent catalog and wire values.
**mobile/lib/shared/theme/buzz_theme.dart**

Defines and validates the versioned desktop-compatible appearance
payload.
**mobile/lib/shared/theme/community_theme_provider.dart**

</details>
## Reproduction steps
1. Sign into desktop and mobile with the same account and join the same
community relay.
2. On desktop, choose a distinctive non-Buzz theme and accent; mobile
should update without a local toggle.
3. Restart mobile and confirm it restores the same appearance.
4. Change the mobile theme and accent and confirm desktop follows.
5. Leave mobile idle or backgrounded through a relay reconnect, then
change desktop again; mobile should resubscribe and catch up
automatically.
6. Switch communities and confirm each community restores only its own
appearance.

- normalize iOS and Android video uploads, attach poster frames, and
improve native video playback
## Validation
- `just mobile-check`
- `just mobile-test`
- `cargo test -p buzz-media`
- Pixel smoke test
- iPhone smoke test
Desktop background uploads moved to #4522 so the two platforms can be
reviewed independently.

Brings the Flutter app's emoji and thread surfaces up to desktop parity.
## Emoji
- **Full emoji-mart dataset** generated from the same `@emoji-mart/data`
set desktop uses (1,870 emoji, 8 categories), committed as an asset — so
shortcodes, names, and keywords are identical across clients. `just
mobile-emoji-data` regenerates it.
- **Rebuilt the tray**: search (a Dart port of desktop's tiered
`emojiSearch` ranking, extended to names and keywords), a
frequently-used section, and one continuous scroll with pinned section
headers. The category rail is a shortcut into that list, not a page
switcher, and spans the full width the search field uses. Custom emoji
share the native glyph size and cell.
- **Reaction pills** match desktop's geometry, and the count shows at 1.
- **Emoji-only messages** render at 36px with 1.45em inline custom
emoji, matching desktop's `emojiOnly` treatment.
- **Positive-emoji burst** ported from desktop's `EmojiBurstProvider`,
suppressed under reduced motion.
## Threads
- **Top-down layout** — head first under the app bar, replies flowing
down, like desktop's thread panel. The old reversed list bottom-anchored
the content and jammed the head against the composer.
- **Tap a channel message to open its thread**; long-press still opens
the action sheet.
- **Live reactions.** The thread's relay query is one-shot and its
`kinds` filter carries only content rows, so a reaction event could not
reach an open thread at all, and `allMessages` was a snapshot frozen
when the route was pushed — a new pill only appeared after leaving and
re-entering, which refetched. The live channel events are now unioned
into the thread's list. The burst is also route-guarded, since the
channel timeline stays mounted underneath and was claiming it first.
- The `+` affordance follows the channel: replies stay bare until they
carry a reaction, and the head keeps a standing `+`.
## Keyboard
A deliberate downward drag past ~48px dismisses the keyboard; short
scrolls leave it alone. Applies to the channel list, the thread list,
and the compose bar (via a raw `Listener`, so it can't steal the field's
tap or selection drags).
True finger-tracking dismissal is out of scope — Flutter only offers
`manual`/`onDrag`, and 1:1 tracking needs a native `UIScrollView` proxy
plus Android's `WindowInsetsAnimationController`.
## Testing
`just mobile-check` and `just mobile-test` pass (965 tests). New
coverage for emoji search ranking, dataset parsing, the emoji-only
predicate, tray scroll/rail behavior, reaction pills and the burst, and
both thread fixes above. `just ci` green.
