/* ─── Rendering hint (.hzo-cv-auto) ────────────────────────────────────
   content-visibility:auto lets the browser skip layout/paint for offscreen
   sections. BELOW-FOLD SECTIONS ONLY — never the hero or anything that can
   start in the first viewport (the hint would delay its first paint), and
   never on containers whose in-page anchors must be measurable on load.
   contain-intrinsic-size reserves ~800px per skipped section so the
   scrollbar doesn't jump as they render in; `auto` remembers the real size
   after first render. */
