   Layer: Reusable UI components (buttons, cards, badges, forms, quotes)

   ARCHITECTURAL NOTE:
   Each component is self-contained under a single BEM block so it can be
   dropped into any page without pulling in page-specific CSS — this is
   what makes the six HTML pages able to share one stylesheet set instead
   of each shipping bespoke styles.
