   win over expression; brand lives in the details.

   Tokens are the single source of truth. Two themes follow the OS,
   not a toggle: this page is opened outdoors to install a plugin.

   Shape scale (documented, applied everywhere):
     chips    -> pill (999px)      small metadata, version, category
     controls -> 12px              buttons, inputs
     surfaces -> 16px              rows, notices, brand mark
