1. Recommended: run python3 server.py next to this page — signed media URLs, no directory listing, hotlink & rate protection. List your files in CONFIG.FILES or playlist.json.
2. Offline: write your filenames into CONFIG.FILES at the top of the script — then even double-clicking the HTML works (unprotected, local only).
3. Or pick the folder / files right here for a quick test:

const CONFIG = {
  CHANNEL: 'KCST·7',
  EPOCH:   null,              // null = today 00:00, restarts daily
  WATERMARK: false,           // faint forensic watermark
  FILES: [                    // ← put your files here, in play order
    'clip-01.mp4',
    'clip-02.mp4',
  ],
};
