## Problem - The player writes the current track name to `now-playing.txt`, but the file still contains stale data after the app is closed. - Downstream tools that read `now-playing.txt` (e.g., overlays or stream widgets) continue to show the last track even though nothing is playing. ## Proposal - Detect when the app window or tab is being closed and clear the contents of `now-playing.txt` before exiting. - Consider also clearing the file if playback stops because the selected folder is closed or the track list empties. ## Acceptance Criteria - Closing the player tab or window results in an empty `now-playing.txt` file. - Clear behavior does not trigger while general playback is paused or when switching tracks. - Behavior works consistently across supported Chromium-based browsers. ## Notes - Ensure the cleanup logic aligns with the File System Access API limitations and handles permission prompts gracefully.
