The "View Channel" button in the tvOS video details panel only dismissed
the player; the channel was never pushed. Delegate to
NavigationCoordinator.navigateToChannel(for:collapsePlayer:) so
UnifiedTabView's pendingNavigation observer appends the destination,
matching iOS behavior and handling extracted/media-source cases.
Replace the tvOS bottom action bar with Settings / Info / Comments /
Next / Close. Settings reuses QualitySelectorView (video, audio,
subtitles, speed); Comments opens TVDetailsPanel directly on the
comments tab; Close stops playback and dismisses.
Debug button is hidden by default and can be re-enabled via a new
tvOS-only Advanced Settings > Developer toggle.
Present the settings sheet as a fullScreenCover with a centered
material card, fix the "Normal" hyphenation, and restyle row selection
throughout the quality selector on tvOS: per-row rounded backgrounds
with focus tint + stroke, vertical spacing instead of dividers, and a
focusable speed-rate menu.
Remove 32 non-dotted keys (16 unused format specifiers, 16 word keys)
and replace with properly namespaced dotted keys following the existing
convention (common.*, player.*, search.*).
Back the in-memory authorCache with a JSON file in ~/Library/Caches/AuthorCache/.
Disk is lazy-loaded on first lookup and saved asynchronously on each cache update.
Capped at 500 entries to prevent unbounded growth.
- Cache author data from video detail API responses (PlayerService, VideoInfoView)
- Replace ChannelView's private CachedChannelHeader with shared CachedChannelData
- Enrich author with cached avatar/subscriber count in VideoChannelRow, TVDetailsPanel, VideoInfoView
