Web SaaS foundation + Replicate for pay-per-inference model access

Same foundation as Web SaaS (hosting, DB, auth, errors) plus Replicate for state-of-the-art models without the GPU management headache. Start with pay-per-inference — Replicate bills per second of compute, so you pay nothing until you have users. Add Lemon Squeezy when you're ready to charge customers. Deliberately omits Resend and Cloudflare for simplicity; both can be added à la carte from the Web SaaS package.
