   Prefix: bd-  |  Accent: cyan --see (perception)
   Renders on the page-level fixed design stage (.mac-fit wrapper,
   components.css): 720×450 desktop, 520×325 under 980px viewport,
   scaled by main.js to fill .mac-screen. Base styles below are the
   720×450 geometry; the @media (max-width: 980px) block is the
   tighter 520×325 geometry. px units, stage-logical.
   Consumes tokens.css + base.css. Redefines nothing shared.
