 * Aira Antivirus — Stage 3: Technology Section Styles
 * Visual Direction: Premium Cybersecurity × AI Infrastructure
 * Strictly adhering to:
 * - tokens.css & primitives.css
 * - frontend-design (cybersecurity-first, zero SaaS clichés, deliberate typography)
 * - frontend-ui-engineering (mobile-first, 4px scale, responsive clamp, 44px touch targets)
 * - better-colors (semantic tokens, verified WCAG AA/AAA contrast)
 * - better-accessibility (visible focus, prefers-reduced-motion, semantic ARIA)
