/* cases.css - /cases/ and /cases/<slug>/ only (WORK-ORDER.md R5, WORK-ORDER-v2 rows 1-13 + R8).
   Loaded via each page's own head slot; every class is prefixed `case-` so nothing collides with
   the shared .hero/.faq/.side/.main/.toc used elsewhere. Reuses site.css tokens (--paper/--green/
   --amber/--ink/--mute/--serif/--sans/--r-card/--r-pill/--nav-h/--pad/--wrap) and utilities
   (.wrap/.btn/.btn-amber/.btn-outline/.h2/.row); no new fonts.
   Motion lives in two places only: CSS keyframes here (hero rail, price card) gated by
   html.cs-motion, and scroll reads in public/components/cases.js. prefers-reduced-motion = the
   final state, no animation (see the end of this file).
   Breakpoints: 640px = card rows / banner art · 768px = hero cut-out · 900px = side column.
   Paragraph rule (row 7): a <p> never carries its own padding or border (a card's padding sits on
   its wrapper), so lines = round(height / line-height) holds for every paragraph. */
