Three-deck DJ console for the browser

• AudioWorklet turntables: sample-accurate varispeed, reverse & real scratching
• Worker-thread analysis: BPM detection, beat grid and multi-band waveforms
• Auto-sync: tempo match plus a phase-locked loop that keeps decks glued
• Split output: master to the speakers, PFL cue to a second device or channels 3/4
• Indexed crate: SQLite full-text search over your local folders, plus Jamendo

Audio needs a user gesture to start. Chromium browsers give the best results (setSinkId for headphone cueing).
