Lark learned to hear chords, suggest a learning path, and track you in time.

• Chord detection in song mode: chromagram identifies strummed chords alongside single notes
• Four chord-strum songs added: Knockin' on Heaven's Door, Stand By Me, Let It Be, Three Little Birds
• Six-stage learning curriculum: stages unlock at 70% accuracy, progress tied to session history
• Beat-aware scoring: timeout scales with BPM, end-of-session shows on-beat/late/slow breakdown
• Procedural cover art: each song gets a unique vinyl or cassette SVG seeded by title and difficulty
• Count-in clicks before the first note, beginner string labels, and stop button during play

The tab view became a proper instrument with real MIDI data and a live playhead.

• Songsterr-style scrolling tab: 6-string staff with a fixed green playhead, notes flow left

• All 73 note songs rebuilt with a note-names-first pipeline for improved tab accuracy
• Timing pill: ON BEAT / LATE / SLOW flashes after each hit to help you lock to the tempo
• LarkChat Safari fix: clip-path circle instead of overflow:hidden, stays visible during songs
• 29 lint errors cleared, metronome extracted to a reusable module, hero layout corrected
