   SVU Events Guide: Site Component Layer
   Project-specific components built on top of the design-system primitives:
   hero, featured slider, filter toolbar, event cards, countdown, detail
   page, footer, scroll-to-top. Category colors form the "vibrant layer"
   required by BWP401 while the base identity stays dark + gold.
