## Summary
- make mobile unread state visible with bold channel names, an animated
Inbox badge, and swipe-to-toggle Inbox rows
- add directional transitions for top-level mobile navigation
- let mobile send while media uploads, with cancellable progress UI
- 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.

**Category:** fix
**User Impact:** Channel groups created on desktop now reliably appear
on Android and iOS on cold start, instead of falling back to the default
ungrouped list.
**Problem:** On mobile cold start, ChannelsNotifier fires ~25
per-channel REQs at once, exhausting the relay's per-connection
rate-limit quota. `ChannelSectionsManager` then gets BOTH its one-shot
history fetch and its live subscription rejected with `rate-limited:
quota exceeded` — and both errors were silently swallowed (`catch (_)`)
with no retry, so the manager kept the local (empty/default) store
forever. Restarting the app repeats the same storm, so Android reliably
lost the race every launch. Captured live on the emulator with
instrumentation.
**Solution:** Track whether the startup fetch and the live subscription
have each succeeded, and retry `_syncWithRelay` with exponential backoff
(2s base, shift-capped, 30s max) until both land. The retry timer is
cancelled on dispose, and previously-swallowed errors are now logged.
Based directly on `main` — independent of #2829 (which fixes the *write*
path: unpublished local edits being clobbered). The analogous retry for
`ChannelSortManager` lives in #2829, since that manager is introduced
there.

<summary>File changes</summary>
**mobile/lib/features/channels/channel_sections/channel_sections_manager.dart**
Extract the startup fetch + live-subscription into `_syncWithRelay`,
track success of each step, and schedule a backoff retry until both
succeed. `_fetchAndMerge` and `_startLiveSubscription` now report
success; swallowed errors are logged; retry timer cancelled on dispose.
`startupRetryBaseDelay` ctor param is test-visible.
**mobile/test/features/channels/channel_sections/channel_sections_manager_test.dart**
New regression tests with a rate-limiting relay fake: remote sections
are adopted after retries; retry stops once fetch + subscription
succeed; dispose cancels pending retries.
</details>
## Reproduction Steps
1. On desktop, create channel groups (sections) for an account.
2. Cold-start the Android app for the same account on a relay with
per-connection rate limiting and enough joined channels to trigger the
REQ burst (~25 channels reproduced it reliably).
3. Before this fix: logs show `fetch FAILED: Exception: rate-limited:
quota exceeded` and the live subscription failing, then silence — the
channel list renders the default ungrouped list forever, surviving app
restarts.
4. With this fix: logs show `startup sync incomplete; retrying in 2000ms
(attempt 1)`, the retry succeeds, and the desktop-created groups render.
## Verification
- Live on emulator-5554 (earlier stacked build of the same logic): cold
start reproduced the manager being rate-limited, then a single 2s retry
succeeding and groups rendering, matching desktop channel-for-channel.
- Full mobile suite run at this exact head (c5f1d9a38): 654 passing; the
4 failures (3× `compose_bar_test`, 1× `channels_page_test`) reproduce on
unmodified `main` (74b63e184) — pre-existing, unrelated. `flutter
analyze` clean on both touched files.

Mobile's ChannelSection model dropped desktop's optional `icon` field, so any
mobile section mutation republished the whole-blob LWW channel-sections event
with every icon stripped — wiping sidebar section emojis on all devices. Now
mobile round-trips the icon through storage/sync, preserves it across all
mutations and the publish no-op check, and renders it in section headers
(native glyph or registered custom emoji; unknown shortcodes fall back to
literal text).
