/*
 * Design Brief: Velonix ← inspired by https://velonixai.io/
 *
 * Structure: header-nav → hero-centered-visual → capability-mosaic → tabbed-platform
 *            → strategy-card-grid → security-split → cta-band → footer-multi-column
 *
 * Hero: centered typography with floating dashboard card visual (not dark gradient orbs)
 * Palette: white/light-gray bands, navy text hsl(222 47% 11%), lime-green accent hsl(97 76% 40%)
 * Typography: Plus Jakarta Sans — geometric, confident fintech scale
 * Motion: fade-up reveals, card hover lift, smooth 0.4s ease-out
