/* FeedSync base layer - reset, element defaults, and the shared component
   vocabulary (the app shell + sidebar, buttons, forms, cards, tables, pills,
   flashes, the impersonation banner). Makes the merchant /app and agency /admin
   look like one product on the light canvas. Consumes tokens.css only - every
   colour/space/radius/shadow is a var(--...), nothing hard-coded.

   S.C.R.A.P.S. physicality lives here: buttons rest with a lip and LIFT on hover;
   inputs SINK (inset) and rise on focus; cards/sidebar carry real depth. Motion is
   tactile and purposeful, disabled under prefers-reduced-motion.

   Load order on every surface: tokens.css -> base.css -> <surface>.css */
