Android was the last job still downloading its world every run: ~3 GB of
SDK/NDK/CMake from Google, a from-source cargo-ndk build, and one monolithic
cache key where a gradle edit invalidated the cargo registry and the Rust
target/ with it. punktfunk-android-ci (content-keyed, LAN registry) bakes
JDK 21 + SDK + NDK + cargo-ndk + sccache; the workflow shrinks to checkout →
two caches → gradle. The cargo-home cache joins the fleet-wide namespace
(same lockfile, same layout — it was the same bytes under a private key),
gradle gets its own key shared with android-screenshots (which stored the
identical content under a second name), and target/ leaves the cache —
sccache covers the three ABI builds now.
Apple: sccache (self-healing ~/.local/bin install + already provisioned on
the mini) covers every cargo invocation build-xcframework.sh makes across
the swift job, the screenshots job and release.yml — three jobs that each
recompiled the same core. screenshots.sh learns PF_SHOT_DERIVED_DATA so CI
pins one stable DerivedData root instead of cold-building into two throwaway
mktemp trees per run (release.yml's disease, same cure), and the Simulators
get shut down after capture (the 846-leaked-sims lesson).

Diagnosed from the first run: only the iPad shots were produced. The runner
lacks an "iPhone 16 Pro Max" device, is headless (no window server -> the macOS
window capture's app window never appears), and the Tier-3 tvOS build-std slice
failed.
- screenshots.sh: shoot_sim now creates a throwaway Simulator (matching device
type + newest available runtime) when the runner has no matching device, so
the iPhone 6.9" shots are reproducible instead of skipped.
- apple.yml: scope the CI job to the two REQUIRED iOS sizes (iPhone 6.9" +
iPad 13"), captured via `simctl io screenshot` (no Screen Recording grant
needed). Drop macOS (headless runner has no window server) and tvOS (build-std
slice) from CI — generate those locally with `tools/screenshots.sh macos tvos`.
Faster, deterministic xcframework build (BUILD_IOS=1 only).

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.
