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.
