- Move supabase/ from packages/db/ to repo root for simpler CLI usage - Use custom ports (553xx) to avoid conflicts with other local Supabase instances - Add --env-mode=loose to turbo dev so root .env vars reach Next.js - Remove hardcoded --port 3000 from next dev (reads PORT env var instead) - Add .env.example with Supabase env var placeholders - Add supabase local state dirs to .gitignore Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
