/* =========================================================
   AZ HOME DESIGN — La ligne de lumière
   Warm, luminous, turnkey luxury. Vanilla CSS.
   Abdelmoughite Zerouali sculpts space with light: continuous
   LED cornices, backlit niches, warm halos. The site is light,
   warm and clear — the hero is the one dark moment, where the
   cornice "switches on" and reveals the room. A warm line of
   light recurs throughout, connecting and revealing.
