/* ════════════════════════════════════════════════════════════════════════════
 * VistoShield homepage hero — animated dashboard preview
 * ════════════════════════════════════════════════════════════════════════════
 *
 * Pure HTML/CSS animation (no JS, no MP4, no images beyond SVG icons inline).
 * Replaces the static shield SVG that used to sit in .hero__visual.
 *
 * Scene loop (24 s total):
 *   0–6 s   Scene 1 — Live attack feed (rows scrolling, threats blocked counter)
 *   6–12 s  Scene 2 — Security score 64 → 92 (animated ring + module badges)
 *   12–18 s Scene 3 — 14 modules grid lighting up
 *   18–24 s Scene 4 — Tagline + EU-hosted seal
 *
 * Bandwidth: ~6 KB CSS + ~2 KB inline SVG → 50× lighter than the smallest
 * MP4 (18 MB) and infinitely faster to first paint.
 *
 * Accessibility:
 *   - aria-label on the wrapper announces "VistoShield dashboard preview"
 *   - All inner text marked aria-hidden (decorative; the hero copy carries
 *     the real semantic content for SR users)
 *   - prefers-reduced-motion media query freezes the animation on Scene 4
 *     (the brand seal — the most static + branded frame)
 *
 * Layout:
 *   - 540×360 default (3:2 aspect ratio, like a laptop screen)
 *   - Scales down via container query (no JS) on narrow viewports
 *   - .hero__visual already has display:none below the breakpoint, so this
 *     never renders on mobile (decorative only)
 *
