Delete declarations that Periphery reports unused on every platform that
compiles them (iOS, macOS, tvOS), including nine views used only by their
own previews. Platform-gated code still used on another platform, device-
only MPV render paths, migration models, CloudKit record names, App
Intents metadata and unused parameters are kept.
The iPhone Duo tabletop layout mirrors every presented frame into the
lower half, blurred and fading out, like a screen standing on a glossy
table. The render view blits a quarter-resolution copy of the display
framebuffer into a ring of IOSurface-backed buffers (no Y flip, so the
surface is already mirrored) and hands it to a CALayer hosted by
MPVReflectionView; the simulator's software renderer feeds the same
layer a flipped CGImage. Off during PiP, for audio-only streams, and
via the new Playback → Foldable → "Reflection Below Video" setting.
- List row hairlines read displayScale from the SwiftUI environment
- MPV render views take contentScaleFactor from traitCollection and
re-apply it on UITraitDisplayScale changes
- ExpandedPlayerWindow scales against the presenting view's own height
- MPVPiPBridge sizes the PiP layer from the container view's window
scene screen (UIScreen.main kept only as a nil-window fallback)
- WideScreenPlayerLayout falls back to the offered geometry size
- Remote control fullscreen state comes from the player sheet's layout
pass via NavigationCoordinator.isWideScreenLayoutActive instead of
screen bounds aspect
- Orientation TODOs for Dynamic Island side detection and
prefersInterfaceOrientationLocked
