/* .hero is a fixed height:100vh sticky pin (hero3d.js scrubs the 3D scene
   to scroll progress over it) — it can't grow to fit content, so on short
   viewports hero-content's width-driven type scale can push the CTA button
   past the clip boundary entirely invisible (measured: gone below ~780px
   viewport height at 1440 width, well within normal laptop-with-chrome
   territory). Trim the vertical rhythm and drop the decorative stats row
   so the headline + CTA always fit.
   Every property below is !important: source order alone proved fragile
   here — two max-width blocks (768px, then 480px) each independently
   re-broke this same fix by setting the same properties later in the
   file. !important makes the short-viewport case win regardless of where
   a future max-width block lands, no file-position discipline required. */
