Website: Next.js app for accounts, linking, who's online, device sign-in and the console

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.
