ChillStep Radio is a fully client-side web application. It automatically discovers your music library by scanning the folder structure when you click SCAN /music or on first load.

1. Music Library
Place albums in /music/album-name/. Each folder can contain MP3 files + optional cover.jpg. Tracks are auto-detected and durations fetched from metadata.

2. Atmospheric Videos
Add looping MP4 videos to /videos/ (global) or inside an album folder (album-specific). Videos are intelligently grouped by name and auto-cycle. Album videos take priority; user selection is preserved when switching albums.

3. Ambient Sounds
Add folders under /sounds/ containing an audio file (mp3/wav) + optional icon. Use the Ambient tab to layer rain, fire, etc. with master volume control. State persists across refreshes.

4. Manifest (Optional)
For faster loads or production, generate manifest.json via the download button after scanning. The app prefers it if present.
