/*
   Quri — component styles.

   Tokens (colour, type scale, spacing) come from theme.json as
   --wp--preset--* custom properties. Everything here is the parts of the
   landing page that those tokens cannot describe on their own: the sticky
   header, the screenshot frames, the format pills, the card grid.

   The page is dark-only by design, matching the app. The app forces the
   dark appearance too — see Docs/theming/table-header-spike.md for why a
   light theme was ruled out there.
