3shelf-kit.js — shared helpers + the composable bookshelf rig.
4
5Part 1 (helpers): side-effect-free pieces used by diorama.js (the self-contained physics
6rig behind the station tables) and by the hero scene: seeded RNG, painted canvas textures,
7the wood-impact sound kit, and the Proxy-node → collision-box reader.
8
9Part 2 (createShelfKit): the interactive bookshelf as a plug-in unit for an externally
10owned scene/camera/canvas (the hero). Ported from diorama.js's shelf slices — kept as a
11deliberate duplicate so the four station tables never depend on hero refactors.
