/* ─────────────────────────────────────────────────────────────────────────────
 * marketing-hero-animated.css
 *
 * Hero variant .mk-hero--wave — full-bleed background with an animated navy
 * wave (Canvas 2D). DS2-strict: only #141c52 / #3f4775 / #eae9ef gradients.
 * Text content overlays the canvas via an absolute-positioned wrapper.
 *
 * Progressive enhancement:
 *   - <picture> fallback PNG is visible by default.
 *   - Canvas element is hidden (opacity 0) until the JS module sets
 *     data-initialized="true" on the wrapper (avoids flash of empty canvas).
 *   - prefers-reduced-motion or absent JS → canvas stays hidden, PNG remains.
 *
 * No glassmorphism, no dark theme default, no palette outside DS2.
