   Tokens alias `--st-*` from studio-theme.css so health follows the
   rust / dark-rust / dark-slate themes the cockpit uses. Aliasing is
   cheaper than a rename pass — every selector below already reads
   `--h-*`, and the studio-theme tokens flip per `body.light-theme`,
   `body.dark-theme`, and `body.dark-theme.dark-slate` for us.
