/*
 * hjLabs.in Enterprise Upgrade Design System
 * v=20260522
 *
 * Single file that elevates the 7 AIML pages to enterprise-grade visuals.
 * All component classes are prefixed `.upgrade-*` to avoid collisions with
 * existing styles. CSS variables live on :root so individual pages can
 * override accents if needed.
 *
 * Composition:
 *   1. Design tokens (color, type, motion, radii, shadows)
 *   2. Hero band (.upgrade-hero) + eyebrow + lead + CTA group
 *   3. Stats band (.upgrade-stats-band) — animated numerals
 *   4. Section frames (.upgrade-section) — numbered headers
 *   5. Cards (.upgrade-card) — hover lift with gradient accent
 *   6. Grid utilities (.upgrade-grid-2/3) — responsive
 *   7. CTA footer (.upgrade-cta-footer) — premium gradient
 *   8. Figure refinements (.upgrade-figure)
 *   9. Floating TOC (.upgrade-toc)
 *  10. Trust badges + chip row
 *  11. Accessibility — reduced motion, focus visibility
 *  12. Mobile — all components ≥ 360px wide
