¿Puedo vibecodear Podia?

Build me a small digital-products store to replace Podia, for selling a few downloads,
not running a course business. Requirements:

- Node + Express + better-sqlite3, server-rendered pages with nunjucks, deployed on my
  VPS behind my existing reverse proxy.
- Products live in products.json: slug, title, price, description, and the file to
  deliver. Delivered files sit outside the web root.
- One page per product plus a /store index. The buy button goes straight to Stripe
  Checkout (keys in .env); no cart, no coupons.
- Stripe webhook on payment: record the order in SQLite (email, product, amount,
  timestamp) and email the buyer a download link via Resend or SMTP (creds in .env).
- Download links are signed tokens that expire after 7 days or 5 uses; an expired link
  shows a resend-by-email form.
- An /admin page behind HTTP basic auth: order list and revenue per product.
- Out of scope: memberships, drip courses, email marketing, and affiliates. Do not build
  customer accounts, the receipt email is the account.
- README: Stripe webhook setup with the CLI test command, and a plain note that
  VAT/sales tax is on me, Stripe Tax exists if it matters.
