/* ==========================================================================
   REAL ESTATE — /real-estate   (design: assets/html/teamian-real-estate (4).html)
   Namespace: everything is scoped under .tre. Loaded via $pageStyles in
   real-estate.php, paired with assets/js/teamian-real-estate.js.

   1. :root, html and body collapse onto .tre — on :root the mock's tokens
      would redefine site-wide values, and its body rules would restyle the
      shared header and footer.
   2. .reveal became .tre-rv on all 26 elements. main.js runs its own
      IntersectionObserver over every .reveal; two observers on the same nodes
      otherwise. Its own state class, .revealed, is untouched — nothing else
      uses that name.
   3. @keyframes wave became tre-wave. Keyframe names are global however the
      selectors are scoped, and style.css already defines `wave`.
   4. overflow-x:hidden became clip on the wrapper. This page has TWO sticky
      scrollytelling sections, and hidden forces overflow-y to `auto`, which
      makes a scroll container and stops sticky dead — the same bug that
      un-pinned the diagram on /education.
   5. Both sticky sections and the hero clear the 76px fixed nav.
   6. Every `Nfr` grid track became `minmax(0,Nfr)` (19 grids).
