/* SyncPanel design system
   ------------------------------------------------------------------
   Light is the base palette; dark is a token swap applied both by system
   preference and by an explicit [data-theme] choice, so the manual toggle
   wins in either direction. Type is set large on purpose: this is an
   operations tool that has to stay readable at a glance.               */
