A new full-screen, touch-first edition of the player aimed at phones through
tablets - no native app, just a web page you can "Add to Home Screen".
Reuses the shared engine + look-ahead scheduler (same player loop as
player.html); new UI is a big pulsing beat display, beat-dot row with accent
grouping, huge BPM (tap to type, vertical drag to scrub), prev/play/next +/-
and tap-tempo, and a bottom sheet for set lists / patch+link loading / volume.
Mobile concerns handled:
- iOS ring/silent switch: navigator.audioSession.type="playback" + a silent
buffer warmup inside the play gesture, so audio isn't muted by the switch.
- Screen Wake Lock while running (re-acquired on visibilitychange).
- PWA: manifest.webmanifest + apple-touch meta + mobile-sw.js (network-first
app shell, passthrough for everything else) -> installable + offline.
Multi-file is fine here since it targets mobile (waives the single-file rule).
- viewport-fit=cover + safe-area insets, no user zoom, touch-action:manipulation,
overscroll-behavior:none; transport buttons flex-share the row so they never
overflow a narrow phone; responsive portrait/landscape, phone->tablet.
- Fullscreen toggle where supported (Android/desktop; iOS uses home-screen PWA).
Wired into build.sh + deploy.sh (page + PWA assets) and added to the index
gallery as PM_M-1 Mobile. New metronome app icons generated in assets/.
Conformance suite unaffected (engine untouched): 47 pass, 1 known.
