Co budujemy.

A worked example replacing the login/signup stub handlers with real Supabase session handling, so authenticate() and createUser() stop returning null.

A reference /api/webhooks/stripe handler covering checkout.session.completed, invoice.paid, and subscription.updated/deleted, wired to a minimal database schema.

End-to-end coverage for the critical UI flows — signup, login, checkout link, language switching — on top of the existing 69 Vitest unit tests.

Drop-in workflows that run lint, typecheck, tests, and build on every PR — the scripts already exist, they're just not wired into CI yet.

A minimal role-based authorization example for /dashboard/* routes, showing how to gate pages and API routes by role once you've wired up real auth.

Full translation coverage across English, Spanish, French, German, Portuguese (Brazilian), and Polish, with routed pages, a language switcher, and automatic hreflang tags.

Visible labels on the hero simulator and dashboard UI clarifying that the metrics, logs, and events shown are illustrative — not connected to a real backend.
