Changelog

Fixed

• ✦Interval fires every 25 ms with a 100 ms lookahead window — clicks are always enqueued in the future, eliminating the ~10 ms setInterval latency that shifted metronome clicks relative to the reference track

Fixed

• ✦Shared AudioContext eliminates clock drift between metronome and reference tracks; nextClickTimeRef lookahead removes setInterval jitter from every metronome click; ref tracks are pre-scheduled at a fixed audio timestamp anchored at countdown start so setTimeout drift cannot shift them

Fixed

• ✦Metronome and reference tracks now share a single AudioContext — both are on the same hardware clock and the same output-latency path, eliminating cross-context drift

Fixed

• ✦Replaced HTMLAudioElement with Web Audio API AudioBufferSourceNode so reference tracks start at the same hardware callback as MediaRecorder — no more audible lag

Added

• ✦Points system — every action earns points: signup, project created, recording submitted/approved/selected, performance published, follow received
• ✦8 levels with distinct names and visual tier badges: Newcomer → Apprentice → Session Player → Collaborator → Performer → Ensemble → Virtuoso → Maestro
• ✦8 badges auto-awarded for key milestones: First Note, Composer, World Stage, Applause, Centurion, Team Player, Rising Star, Maestro
