   LuminaThera — Event Enhancement Styles
   
   Design system styles for dynamic event UI elements:

     • Filter bar and filter pill controls
     • Micro-animations (fade-in, filter transitions)
   
   Companion to design-system.css — uses the same tokens and

     (default)  — open / available slots
     --low      — few remaining spots, draws attention
     --closed   — sold out / registration closed
