/* Phase 3 background-depth / glass-calibration experiment.
   Decorative motifs borrow from design + print production: crop marks,
   registration targets, modular layout grids and offset paper/frame outlines.
   They remain low-contrast and sit behind content so glass translucency can
   be judged without competing with portfolio artwork or copy. */
