Phase 1 of the player panels redesign:
- New PanelSettings model (pages, regions, layout mode, default
visibility) stored as an optional field on PlayerControlsLayout with
an effectivePanelSettings accessor; lenient Codable so future page
types and settings payloads never corrupt saved presets.
- New Views/Player/Panels content engine: PlayerPanelContentView
renders a page bar plus the selected page (info, comments, related,
chapters, queue, tracks), with runtime hiding of empty pages.
- PortraitDetailsPanel and FloatingDetailsPanel now host the shared
content instead of their duplicated info bodies; drag machinery,
pills, and fades are untouched.
- Comments list extracted into CommentsListContent shared by the
overlay and the comments page; comments pill routes to the comments
page (expanding the portrait panel) when the page is enabled, and
falls back to the overlay when it is not.
- Tracks page embeds QualitySelectorView via a new isEmbedded mode.
- Deleted the unused video info bodies in ExpandedPlayerSheet+VideoInfo
and the dead PlayerInfoTab model.
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.
