Stack Selector
Choose tech stack automatically. User doesn't decide.
Decision Tree
What type of app?
├─ Web app with auth/db

│ ├─ Heavy backend logic? → fastapi-postgres
│ └─ Default → nextjs-supabase
│
├─ API/Backend only
│ ├─ Python/ML focus? → fastapi-postgres
│ └─ Edge/serverless? → hono-drizzle
│
├─ Landing page / Marketing
│ └─ → landing-page (static)
│
└─ Unsure → nextjs-supabase (most flexible)
