When nothing is queued and the history and now-playing sections are
hidden or empty, show the same placeholder as the queue sheet instead
of a blank list.
Below Previously Played in the queue page settings; off by default, so
the queue page lists history and up next without the playing video.
With it off the page opens scrolled to Up Next.
Phase 5 of the player panels redesign:
- Per-page element toggles now rendered and editable for every page:
comments (author avatars), related (thumbnails), chapters (thumbnails),
queue (previously played section), tracks (video/audio/subtitles/speed
sections)
- Page bar labels toggle (icons-only bar shows the selected page's name)
- Layout mode schematic diagram in the details panel settings
- NEW badge machinery for future page types (versionAdded on PanelPageType)
- Typed per-page settings accessors on PanelPageConfiguration and VM update
helpers for each page kind
- Unit tests for per-page settings round-trip and accessor fallbacks
The standalone quality selector sheet is unaffected: section gating defaults
to everything visible and only the embedded tracks page passes preset
settings through.
Phase 0 of the panels redesign, extraction only, no behavior changes:
- Unify comments loading on PlayerState: loadComments/loadMoreComments
become the single loader, used by both the player sheet preload and
the comments overlay (which previously had its own duplicate copy).
- Extract PanelResizeGrabber from FloatingDetailsPanel into the new
Views/Player/Panels/ directory.
- Extract the shared queue list from QueueManagementSheet into
QueueListView plus QueuePlaybackActions, reused by the tvOS panel.
- Remove the no-op wideLayoutPanelAlignment accessor from the settings
view model; the player reads the panel side from SettingsManager, so
the preset field was dead. The Codable field stays so old presets
decode.
