/* ============================================================
   KitQuarter rebuild additions
   1) Prose glue for extracted content (old pages use plain
      semantic HTML inside their sections, sometimes wrapped in
      a .content-prose div).
   2) Form element styling inside the calculator card, so the
      preserved forms (which carry their original classes) look
      like the approved design.
   3) A small legacy utility layer: the class tokens the
      preserved forms and calculator scripts use at runtime.
      Only layout, spacing and base color tokens are defined;
      dark/hover/focus variants of the old design are not.

/* ============================================================
   Phase A canonical overrides (this layer loads last on purpose)
   - .hidden utility the filter/menu scripts toggle
   - category grid fits all 7 real categories plus Everyday (4 x 2)
   - backgrounds for the 2 category icons generated for this rebuild
   - one canonical pop-card layout (the samples evolved it three ways)
   - homepage tip demo styles (the sample homepage dropped the demo;
     the live page has one, so the rebuild styles it in the same system)
   - prose-static for extracted sections that carry their own headings
