Initial commit: Music Hub collaboration platform
Full-stack music production collaboration tool with: - SvelteKit frontend with Design System (CSS vars, 8 shared components) - Hono API with auth, projects, tracks, versions, comments - PostgreSQL + Drizzle ORM (8 tables, roles, permissions) - S3-compatible storage with presigned upload URLs - wavesurfer.js audio player with waveform visualization - A/B version comparison with synchronized playback - Timestamped comments with threading and resolve workflow - Magic Link authentication with Resend email integration - Background audio processing (ffmpeg transcode + waveform peaks) - Role-based access control (Owner, Engineers, Artist, Label, Management, Viewer) - Toast notifications, skeleton loading, responsive layout - Docker deployment setup (API + Web + Postgres) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
