Environment Variables

File Strategy

File	Git Tracked	Purpose
.env.development	Yes	Local Supabase defaults (localhost)
.env.production	Yes	Production key names only (values empty)
.env.local	No	Personal overrides (Supabase Cloud keys, etc.)

How It Works

• next dev automatically loads .env.development
• next build automatically loads .env.production
• .env.local overrides all environments (highest priority)
• Vercel deployment: set environment variables in Vercel dashboard
