dig.js: enter a crate → records stand packed in a bin; scroll/drag riffles a damped
cursor through them; each sleeve hinges forward at its bottom edge as you pass (smoothstep
wave); tap the front sleeve to pull it out and inspect (price/condition/add-to-cart panel).
Depth-LOD cover loading (±8 around cursor). Procedural fwip/thunk audio, no asset files.
Wired into index.html: click crate → dig scene; render loop branches on dig.active.
