/* ==========================================================================
   AEO · GEO · SEO — /aeo-geo-seo   (design: assets/html/aeo-geo-seo (4).html)
   Namespace: everything is scoped under .tgs. Loaded via $pageStyles in
   aeo-geo-seo.php, paired with assets/js/teamian-aeo-geo-seo.js.

   Rebuilt from the (4) mock, which replaced the (1) mock this page was first
   built from. It is a dark design now, with one light section. What changed:

   1. :root and `body` collapse onto .tgs. On :root the mock's tokens would
      redefine --line, --text and --accent site-wide; the body rules (a #0a0a0a
      background, #f5f5f4 text) would black out the shared header and footer.
   2. .reveal became .tgs-rv on all 45 elements. main.js runs its own
      IntersectionObserver over every .reveal and toggles .is-visible, while
      this page's observer toggles .in — two observers, two state classes, same
      elements. `.in` itself is kept; main.js never touches it.
   3. Elements that start hidden do so only under .tgs-js, set inline at the top
      of the page. Both the hidden and the revealed state carry the prefix so
      neither can outrank the other.
   4. The reduced-motion block is scoped to `.tgs *` rather than dropped. It
      looked like the usual `*` box-sizing reset to the scoping pass, but it is
      the motion guard — losing it would have handed those visitors every
      animation on the page.
   5. Every `Nfr` grid track became `minmax(0,Nfr)` (16 grids). An fr track's
      automatic minimum is min-content; that is what pushed a hero column
      off-screen on /ai-calling.
   6. The `*` box-sizing reset and `html{scroll-behavior}` are gone — Tailwind
      preflight and style.css already own both.
   7. .hero clears the 76px fixed nav.

   The five AI-engine logos the script draws are real files in assets/img/
   (engine-*.png) rather than ~40 KB of base64 inlined in the page.
