/**
 * Aniplay — Shared Skeleton Loading System
 * Replaces the removed global page-loader (a top progress bar + spinner
 * that could visually read as "stuck loading" — see project handoff,
 * 2026-08-11). Skeletons show the SHAPE of real content while it loads,
 * in place, instead of a separate blocking/overlay indicator — nothing
 * here ever intercepts clicks or blocks navigation.
 *
 * Usage: give any placeholder element class="skel-line"/"skel-block"/
 * "skel-circle"/"skel-card", swap it for the real content once loaded
 * (or toggle a wrapper's [data-loading] attribute — see .skel-hide below).
 * Respects prefers-reduced-motion (shimmer becomes a static tint).
