The U / Esc / F1 / N caption chips next to the HUD action buttons
are meaningless on a touch device and visibly clutter the
narrow-viewport action row (visible as "Esc A [] N" in the v0.22.3
screenshot). `spawn_action_button` now rebinds `hotkey` to `None`
under `#[cfg(target_os = "android")]` so the chip-spawn branch is
skipped on touch builds.
Menu / Modes chevrons are unaffected — they indicate dropdown
behaviour and still apply on touch. Other hint surfaces
(onboarding, pause modal Esc hint, mode-card chips, replay
footer, modal toggle chips, help screen) live behind navigation
and are tracked as a P3 sweep in PLAYABILITY_TODO.md.
Closes P1 #1 of docs/android/PLAYABILITY_TODO.md. 855 engine
tests pass; clippy clean.
