apps/web: Next.js 16 (App Router), Tailwind 4 and shadcn/ui, light and dark from the system. Pages render on the server and call the API with Eden Treaty (typed by @t5de/api), forwarding the visitor's cookie; forms use server actions; sign-up, sign-in and sign-out use Better Auth's React client. /api is rewritten to the API so its cookies are first-party. Who's online follows the API's event stream (Next's gzip is off: it held the stream back). Standalone output with a Dockerfile; deploys to Vercel as is.
