Claude for Indie SaaS

Scaffold a production-ready Next.js (App Router) project for the following product:

Product: {{1-line description}}
Core jobs the user does: {{list 3 to 5}}
Auth: {{Clerk | Auth.js | none}}
DB: {{Postgres (Neon) | SQLite | Supabase}}
Payments: {{Stripe Checkout | Lemon Squeezy | none}}
Hosting target: Vercel

Generate, in this order:
1. `package.json` with pinned versions for the latest stable Next, React, Tailwind v4, Drizzle (or chosen ORM), and the auth/payment SDKs.
2. File tree (no code yet) with `app/`, `lib/`, `db/`, `components/`. Note which routes are public vs protected.
3. `db/schema.ts` with the minimum tables to support the core jobs above.
4. The first 2 routes end-to-end (page.tsx + server action + DB call).
5. A `README.md` with setup, env vars, and `npm run dev` instructions.

Constraints: no class components, no `getServerSideProps`, no axios. Server components by default. Tailwind utility classes inline. Single source of truth per concept (no parallel "old" and "new" patterns).
