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).
