Framer + Spotify (Multi‑user) — Starter (Fixed)

This patch uses .js files and a modern vercel.json so Vercel picks the Node.js 20 runtime without the legacy "now-php" error.

Deploy

1. Push this folder to GitHub, then import to Vercel or deploy via CLI.
2. Set env vars in Vercel:
   • SPOTIFY_CLIENT_ID
   • SPOTIFY_CLIENT_SECRET
   • APP_URL = https://YOUR-APP.vercel.app
3. Add Vercel KV integration to the project (Storage → Add Integration → Vercel KV).
4. In Spotify Dashboard add Redirect URI:
   • https://YOUR-APP.vercel.app/api/callback
5. Visit /api/connect and approve. Copy your public URL.
