   COMPONENT LIBRARY STYLES
   Plain CSS (no @apply — the Tailwind Play CDN can't process directives in
   external stylesheets, it only scans class attributes in the DOM). These
   classes are the semantic vocabulary every page composes with: pair them
   with Tailwind utilities for layout, use these for identity/behavior.
