/**
 * Orsozox Liquid Glass — article pages, "premium" pass.
 *
 * Design intent: the article should read as a stack of physical glass panes
 * floating over a lit background, not as a flat white box. Depth comes from
 * three cheap ingredients rather than heavy blur:
 *
 *   1. Layered gradients  — an accent wash above, a neutral falloff below.
 *   2. Edge lighting      — a 1px specular top edge + a soft inner glow.
 *   3. Real shadows       — a wide ambient shadow plus a tight contact one.
 *
 * Performance contract (unchanged from v1, this is what keeps it fast):
 *   - No extra network requests: no icon fonts, no images, no webfonts.
 *   - Animation only on transform / opacity / background-position.
 *   - Every backdrop-filter sits behind @supports AND `html:not(.orsz-lite)`,
 *     so a weak phone gets the same layout with the expensive parts off.
 *   - Assets load on single posts only.
 *
 * @package Orsozox_Core
