Dialogue Captions adds an ambient MMO-style dialogue overlay to YouTube videos.

Instead of traditional disappearing subtitles, captions are displayed as persistent dialogue bubbles in a movable translucent panel. Users can revisit previous lines, click caption bubbles to seek playback, and follow conversations more naturally during videos, podcasts, streams, essays, and music.

Features:
- Persistent subtitle history
- Clickable caption bubbles for timeline seeking
- Ambient translucent overlay UI
- Adjustable text size and opacity
- Local-only processing in the browser
- No accounts, analytics, or external servers
- Works directly on YouTube watch pages

The extension reads existing YouTube caption/timed-text data locally to improve subtitle readability and conversational flow. No video or caption data is transmitted externally.
