/* ═══════════ YARAAV PREMIUM — layered 3D glassmorphism design system v7 ═══════════
   Visual language adopted from the official YARAAV design reference:
   deep near-black brown base · bronze/copper metallics · translucent layered glass
   · edge illumination · aurora + light beams + horizon glow · fine grain.
   One system, two fully independent themes (data-theme on <html>).
   v7: instant theme switching (zero white flash) · GPU-cheap background
   (no giant blur filters — softness baked into gradients) · self-hosted
   Vazirmatn · new official emblems · perf-first animation layers.   */
