   Command-strips presentation - styles

   Palette and typography are the vividhome design system (assets/css/
   design-system.css); the tokens are restated here instead of imported so
   the frame keeps working if it is ever served on its own. Fonts come from
   ../css/fonts.css, which the shop page has already put in the HTTP cache.

   The original delivery shipped one minified sheet plus a "readability pass"
   block at the end that re-declared ~40 of its own rules with bigger type.
   Both are folded together here - one declaration per property.
