/* package-site chrome.
   The whole site skin: header, drawer, sidebar, page, playground, controls,
   code, tables, pager, credit. Every form control in the UI is styled once,
   here, so a select in the header and a select in a playground are the same
   object. A package changes the look by setting tokens, never by restyling
   these rules — out-specifying this file is how two sites drift apart.

   Tokens a package may set (defaults below are a neutral warm grey):
     colour   --bg --fg --muted --line --line-strong --panel --code --accent
              --mark --up --down
     type     --f-ui --f-head --f-mono --size --line-height
     shape    --radius --radius-lg --focus-width --focus-style
     stage    --stage-bg --stage-ink --stage-pad
     nav      --nav-width --nav-current-bg
