Per docs/DIG_FLIP_HANDOVER.md — same createDig contract, zero index.html changes:
- real format sizes + packing by thickness (FMT map; LP-only today, CDs inevitable)
- secondhand lean: per-sleeve seeded jitter (rotation.z + position.x)
- crate drawn around the stack with the lower front lip you flip over
- covers trickle-load (fillQueue 120ms) + near-cursor priority window (-10..+15)
- pull presents at arm's length on the view axis (-0.1, 0.23-h/2, 0.12, rot -0.33)
- Add to cart -> localStorage rg_cart (SKU-keyed, matches /shop/checkout), then
the stack re-packs closed — no gap
- fix: dig camera aspect was NaN if the window loaded 0x0 and never resized;
guard + resize listener (latent in ancestor + THRIFTGOD)

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.
