/* ============================================================
   Level 13 — Носки по парам

   Scene only: a bed in late afternoon and an open drawer organiser
   with four linen-lined compartments. Everything that moves is
   handled by shared/puzzle.css.

   The drawer is deliberately built out of many low-opacity layers
   rather than a couple of flat fills, because the first nine levels
   are painted and a flat tan rectangle next to them looks like a
   placeholder. Wood gets two grain passes and an end-grain wash;
   the lining gets a woven weft, a fibre grain and its own ambient
   occlusion where the wall meets the floor of the compartment.
