   LANDING — the public-facing page. Deliberately its own visual language:
   monochrome, technical, telemetry-flavored — distinct from the internal
   app's light dashboard theme (tokens.css). Two type families only: the
   licensed grotesque already hosted for the app (headlines, body) and the
   system monospace stack (labels, buttons, data readouts, nav) — no webfont
   CDN, nothing this page depends on that isn't already sitting on disk.
