Fold music player (prop)

A one-screen music player for the Galaxy Z Fold 8 folded (cover) screen, built only from the "Music App" frame in Figma (file jO4VrQnb9mAVd7SkmDKv9Y, node 4:9, 523×847).

The only things that work are the red play/pause button, the progress bar (tap or drag it to jump to any point in the song) and the album cover and the home button in the bottom nav (tap either to reset to 0:00, paused). Shuffle, skip, repeat, back, heart and the rest of the bottom nav are artwork.

• Title (big title and header): "Jamme, Jamme"; subtitle: "Let’s Go to the Top" (the Figma frame says "Jamme Jamme" / "Let’s Go"; changed on request). The album cover is a "Jamme, Jamme / Napoli · Italia" poster (assets/cover-jamme-v2.jpg).
• Opens paused at 0:00. Play runs the progress bar and clock to 1:34, then returns to 0:00.
• Audio: drop a file named song.mp3 next to index.html and it plays in sync (its length replaces 1:34). Without it, a silent timer drives the screen.
• ?t=85 starts at 1:25, ?play=1 starts playing.
• No fake status bar: the strip above the header is left empty, as in the Figma frame.
• Keys: Space plays/pauses, R resets to 0:00.
• Full screen, no status bar: installed from the home screen it opens full screen (manifest display: fullscreen, falling back to standalone), and in a browser tab the first tap goes full screen. The first tap also keeps the screen awake.
• sw.js is a pass-through service worker; it's there so Chrome on Android installs the player as a real app (in the app drawer) instead of a home-screen shortcut.

The layout scales the Figma frame to fit any screen: the top bar sticks to the top, the nav to the bottom, and the player sits centred between them.
