/**
 * hero-variants.css — Phase 7 — hero carousel V1–V5 visual styles.
 *
 * Ported verbatim from design_handoff_koallabs_homepage/prototype/hero-variants.css.
 * Loaded only on / via koallabs/homepage. Activation logic lives in
 * js/hero-carousel.js (Drupal.behavior — random variant per page-load per D-07).
 *
 * V1: Shadow-AI audit terminal (CSS @keyframes blink + pulse)
 * V2: Cycling pain phrase (JS setInterval swap; CSS transition .cycling.out)
 * V3: Before/After columns (CSS @keyframes float on .tool-chaos .chip)
 * V4: Readiness gauge mockup (CSS transition width 1.2s cubic-bezier(.2,.8,.2,1))
 * V5: Data-flow SVG (SMIL animation — CSS only styles the container)
 *
 * Reduced-motion (D-12 handoff default): all decorative animations stay on.
 * Mobile <900px (D-12): handoff defaults preserved verbatim.
