v2.0.0 - React/Node.js rewrite

v2.0.0 — Full Rewrite

A complete ground-up rewrite of Spotify Viber, moving from a Python/Tkinter desktop app to a modern web stack.

What's new

• React + Vite frontend — runs in the browser, no desktop app required
• Node.js/Express backend — handles Spotify OAuth token exchange securely
• Real-time audio sync — uses the Web Audio API (AnalyserNode + FFT) on your microphone or system loopback for near-zero latency beat detection, replacing polling-based approaches
• 3 visualizer modes:
  • HALO — three layers of flowing Bézier curves in polar coordinates, morphing to the music
  • AURA — a full-screen radial light gradient that pulses like a lava lamp
  • BARS — a classic neon 64-band equalizer
