/* =====================================================================
 * Landing hero carousel + home-page scroll reveals.
 * ---------------------------------------------------------------------
 * Consumed by core/website/templates/website/indexv4.html together with
 * static/boiler/js/landing-hero.js. Plain CSS (no Tailwind build step —
 * the theme's utility CSS is pre-purged, so nothing here relies on it).
 *
 * Structure:
 *   1. Hero swipers (text + visual), typewriter caret, pagination, pause
 *   2. .hero-mock — the morphing mock-workspace browser frame (slide 1 fx)
 *   3. Per-app vignettes (keyframes run only under .hero-anim-run)
 *   4. Scroll-reveal system (gated on .js-reveal-ready + reduced motion)
 *   5. Reduced-motion + mobile overrides
 * ===================================================================== */
