NextJS Mailtrap SaaS Starter

This starter exists to give learners and indie hackers a real, working reference for how a modern SaaS app fits together — auth, Stripe billing, multi-tenancy, and email, wired end-to-end on Next.js. Rather than leaving email as an afterthought, it uses Mailtrap to handle sending, so transactional messages actually land reliably from day one. It's blank-slate scaffolding, not a finished product: clone it, drop in your own logic, and you're shipping within the hour.
