/* Shared interface pieces for every surface. Loaded after tokens.css and

   Button semantics (one primary per screen):
     .btn-primary    the main action on the screen (brand red)
     .btn-secondary  a supporting action (water blue)
     .btn-danger     delete, deny, reject, cancel a booking, deactivate
     .btn-quiet      an outlined neutral action
     .btn-link       an inline text action (readable on light surfaces;
                     the header variants recolour it where needed)
   Every button is at least the touch token tall and shows a disabled state. */
