/* KERN / MONO — alternatieve native route
   A high-key studio contact sheet. The page itself has no accent colour: every hue on it
   comes out of the Blender renders. Structure is carried by a fixed mono index rail, a split
   opening, and a strict alternation of chalk reading pages and near-black photographic bands. */
