/**
 * Dinova Studio — Page preloader.
 *
 * A full-screen fixed overlay shown while the page loads, then faded out by
 * preloader.js (which adds .is-hidden). FAIL-SAFE: a CSS fallback animation hides
 * the overlay even if the script never runs, so the page is never stuck behind it.
 *
 * Colours come from settings-derived vars on .qdst-preloader: --qdst-pre-bg,
 * --qdst-pre-color, --qdst-pre-image-width. RTL-safe (logical properties only).
