   Auto-Cuan — UI theme layer
   =========================================================================

   Loaded AFTER the inline <style> block in index.html so it wins without
   !important. It is deliberately a restyle of the component classes that
   already exist (.panel, .action-card, .dashboard-hero, .empty-state, …)
   rather than new markup: the app converges on one card language, one radius
   scale and one type scale without touching behaviour.
