/**
 * Aqua Studio Theme — assets/css/motion.css — v1.1.0 — Job 2026-07-04-egfs-launch wave 2
 * Living Water motion system. Source: clients/egfishstore/creative/motion-spec.md
 * (Kenji, Motion) — production CSS pasted verbatim, integrated by Ali.
 * Enqueued after aqua-studio-tokens in functions.php. Additive only — does
 * not edit or override any rule in style.css or rtl.css.
 *
 * Contents:
 *   0. Hero structural layout (Ali addition — style.css never defined
 *      .aqua-hero/.aqua-hero__media/.aqua-hero__copy box model; these are
 *      the minimum positioning-context rules the motion layers below need
 *      to stack correctly behind the copy. Not part of Kenji's spec verbatim
 *      — flagged here so the boundary between "spec, unchanged" and
 *      "structural prerequisite" stays visible.)
 *   1. Hero water motion (light shafts / particulate drift / caustic shimmer)
 *   2. Micro-interactions (card hover, badge fade-in, CTA ripple, nav chip underline)
 *   3. Coming-soon page motion
 *   Reduced-motion fallbacks are inlined under each block, verbatim from spec.
