/*
 * Aurelux Web Development — home
 *
 * Light by default. Depth comes from CSS 3D: a perspective stage, slabs placed
 * on the Z axis, and one custom property (--awd-scroll, 0 → 1) that the script
 * in page-home.php writes per frame. Nothing animates unless the html element
 * carries .awd-3d, which is only added when motion is allowed and the viewport
 * is large enough to be worth the effect. Without JavaScript this file still
 * lays the page out — it just sits still.
