/* envitel.ai — 2026 rebuild, design iteration 3.
   House system: paper ground, navy ink, gold accents, STIX Two Text display.
   Alternating section grounds, scroll reveals (JS-gated, reduced-motion safe),
   differentiated CTAs: gold = get the overview (lead), navy = talk to us,
   ghost = secondary navigation. Light-only by brand decision. */
