/*
 * Design Brief: Orbivex ← inspired by https://www.onetrust.com/
 *
 * STRUCTURE: announcement-bar → header-nav → hero-statement-split → platform-statement-band
 *   → solutions-masonry-grid → trust-testimonial → capabilities-tabbed → tech-split-reverse
 *   → cta-band-dark → footer-multi-column
 *
 * OneTrust cues: light-first palette, mint accent used sparingly on CTAs/signals,
 * left-aligned confident typography, governance platform positioning, solution category grids,
 * testimonial social proof, resources/insights rhythm, restrained enterprise motion.
 *
 * TOKENS derived from reference analysis — NOT generic dark-gradient defaults.
