Station Trash Compactor & Cargo Packing — 2D Shelf Packer

Every day a space station's crew produces a stream of dry trash — food packaging, wipes, used filters — that has to be compacted and shelf-packed into a disposal cargo vehicle before it undocks and burns up on re-entry. This 2D simulator generates that daily waste stream from a crew-size and per-person rate you control, compacts each bag by an adjustable ratio, and packs the resulting bags into a pannable, zoomable 2D cargo bay cross-section using a real first-fit shelf-packing heuristic, with live readouts for area utilization, mass loaded, a daily-volume history sparkline, and a days-until-full countdown to departure.
