/* ============================================================
 * animations.css — site-wide motion polish
 * ------------------------------------------------------------
 * Subtle, tasteful motion tuned to the dark deathcore aesthetic:
 * slow ease-outs, low-opacity fades, small translations, and a
 * faint red-glow on interactive focus. Kept in one file so it's
 * easy to tune or disable, and fully gated behind
 * prefers-reduced-motion for accessibility.
 *
 * Loaded AFTER the bundle + auth CSS so these transitions layer
 * on top without fighting layout. Nothing here changes position
 * or size at rest — only motion on hover/tap/entrance.
