Stream reliability
- Default to the stage-2 presenter (VTDecompressionSession + CAMetalLayer): it detects
and recovers a wedged decoder, where stage-1's AVSampleBufferDisplayLayer freezes hard
on a lost HEVC reference frame with no app-side recovery (confirmed Apple limitation).
Stage 1 is now a DEBUG-only presenter toggle, plus the automatic no-Metal fallback.
- Stage-2 pixel-perfect: render the drawable at the decoded size (shader stays 1:1 =
identity) and let the layer's contentsGravity scale via the system compositor — the
same path stage-1's videoGravity used — instead of scaling in-shader.
- Loss recovery in both pumps is now a persistent awaitingIDR want, retried until an IDR
actually lands, so a keyframe request swallowed by the throttle can't strand a frozen
frame; 100 ms keyframe throttle to match the Android path.
- Fix "Publishing changes from within view updates": defer the HostStore writes out of
the .onChange(of: model.phase) callback.
- Move AVAudioSession setActive/setCategory off the main thread (async on a shared serial
queue) to stop the UI-stall warning.
Controllers
- Rumble: capped-exponential backoff when the gamecontrollerd.haptics XPC breaks (-4811)
so a transient server interruption self-heals instead of cascading; playsHapticsOnly so
a controller engine doesn't join the always-active streaming audio session.
- Host cards: iPad pointer "magnet" hover effect; iPhone press scale + light haptic.
UI / design
- Ship Geist (SIL OFL 1.1) as the app font (bundled OTFs + registration), with the
license surfaced in Acknowledgements.
- Restructure iOS/iPadOS Settings into a category NavigationSplitView; resolution wheel
with custom-resolution entry; 10-bit HDR toggle in Display.
- Industrial host-card redesign (left-aligned, bold, brand monogram tiles).

A DEBUG-only "shot mode" renders one mock-populated screen full-bleed
(PUNKTFUNK_SHOT_SCENE=<name> -> ScreenshotHostView instead of ContentView),
so the OS can screenshot the REAL, fully-rendered UI. tools/screenshots.sh
drives it: screencapture for the mac window, `simctl io booted screenshot`
for the iOS/iPad/tvOS Simulators, at exactly the App Store Connect sizes.
ImageRenderer was tried first and rejected: it can't rasterize this app's
chrome (NavigationStack, Form/TabView, Liquid-Glass/NSVisualEffect all render
black or the "can't render" placeholder). Capturing the live window/Simulator
avoids that. Only the stream hero is synthetic (StreamView needs a live
connection) - a synthwave frame + the real glass HUD, overridable via
PUNKTFUNK_SHOT_HERO.
CI: a new `screenshots` job in apple.yml builds the iOS (+ tvOS best-effort)
xcframework slices, runs the harness per platform best-effort, and attaches
the result as a single zip artifact (punktfunk-appstore-screenshots). It is
isolated from the build/test job and skipped on PRs, so a capture gap (missing
Simulator runtime, or no Screen Recording grant for the mac window capture)
never reds the core signal.
Generated PNGs (clients/apple/screenshots/) are gitignored.
