   Homepage category cards.
   Loaded only on the homepage via pages.extra_css_json.

   Turns the legacy <ul class="categories"> into a responsive grid of cards
   with a colourful icon chip, name, and a single descriptive line. Uses the
   theme :root variables so light/dark both look right. Rotating accent hues
   give the grid colour without needing per-category overrides.
