Adds an interactive floating panel to easily apply "Slowed" or "Nightcore" effects to tracks.
- Playback Speed Control: Precision slider from 0.5x to 1.5x.
- Pitch Preservation: Toggle to keep the original pitch or let it deepen/raise with the speed (true slowed/nightcore effect).
- Presets: Quick buttons for standard Slowed, Nightcore, and Reset.
- Persistent Settings: Preserves your chosen speed and pitch settings across track changes seamlessly.
This plugin operates strictly via the HTML5 <video> element properties (playbackRate and preservesPitch). It explicitly avoids the Web Audio API to guarantee 100% compatibility with other audio-hijacking plugins (like native Equalizers or Crossfade).
