   css/chest.css - treasure chests (DECISIONS 501, docs/PLAN-CHEST.md; the proposal's docs/img/chest/src/chest.css).
   --------------------------------------------------------------------------
   On the map: the chest is an object like the sign and the ferry (js/scene/actors.js, js/scene/scene.js setChest),
   drawn by a strip of frames that scripts/slice_chest.py cut from the owner's sheets into assets/scenes/objects/:
   cells of 120 x 148 px, the chest's base 48 px wide and centred, its foot on y 132 of the cell. A ball chest strip
   has 10 cells (idle 1-4, open 1-6), the stone chest 22 (idle 1-8, then 14 frames that open it on nothing and shut
   it again), the sparkle burst 8 cells of 160 x 160.
   The window: the Minecraft-like grids of js/ui/chest.js in openModal({wide, sheet}) - the chest's slots on top, your
   Bag below.
