   Red Kite — redkite.info
   The public site. Nothing operational lives here (Specification.md, head of document).

   The palette, the typefaces and the rule that colour never carries state alone are inherited from
   documentation/Design-Language.md and src/RedKite.Web/src/styles.css. The marketing page and the
   product deliberately look like the same object.

   Deliberately single-theme. The hub is a dark instrument and a HUD in light mode is nonsense; every
   colour is painted explicitly so the page never borrows a host's ground.

   The screens — a faithful reproduction of the hub's Now screen.

   Every class here is prefixed `shot`. That is not fussiness: this project has already paid for the
   alternative once. `.grid` was the dashboard's three-column layout, and reusing the bare name for
   something else applied `display: grid` to every table on the page and tore the headers away from
   their rows — silently, with a passing typecheck. This stylesheet already owns `.card`, `.chip`,
   `.figure` and `.brand`, all of which the hub also uses for something different.

   The markup that uses these mirrors src/RedKite.Web/src/App.tsx. The figures in it are examples.
