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
