/* ==========================================================================
   HEALTHCARE — /healthcare   (design: assets/html/teamian-healthcare (4).html)
   Namespace: everything is scoped under .thc. Loaded via $pageStyles in
   healthcare.php, paired with assets/js/teamian-healthcare.js.

   1. :root, html and body collapse onto .thc — on :root the mock's tokens
      would redefine --ink and --line site-wide, and its body background would
      restyle the shared header and footer.
   2. .reveal became .thc-rv. main.js runs its own IntersectionObserver over
      every .reveal and toggles .is-visible, while this page's toggles .in.
   3. @keyframes wave became thc-wave. Keyframe names are global however the
      selectors are scoped, and style.css already defines `wave`.
   4. Elements that start hidden do so only under .thc-js, on both the hidden
      and revealed state so neither outranks the other.
   5. The `*` box-sizing reset is dropped (Tailwind preflight owns it) but the
      `*` inside the reduced-motion query is KEPT and scoped to `.thc *` — that
      one is the motion guard, not a reset.
   6. Every `Nfr` grid track became `minmax(0,Nfr)` (9 grids).
   7. .hero clears the 76px fixed nav.
