/* Easydone Studio signature, option 2 layer ("studio lights"), DES-08, 26 Sep 2026.
   Load after studio-signature.css. Adds dark "night" sections and dark cards: near-black green
   rather than easydone.work's deep-green blocks, with the work lit by a soft gold spotlight.
   No cutting-mat grid or crop marks on night surfaces. */
