/* The public site speaks the dashboard's language: tokens are copied from
   ui/src/index.css, which in turn follows docs/ui/design-system.md and the
   approved A2 cut. The rule that matters is the same here as there — status
   hues express instance lifecycle and nothing else. A "live" green on a
   marketing button would teach visitors the wrong meaning before they ever
   open the dashboard. */
