How many complete SETS of one product fit in a single container? A product is 1+ carton types with qtyPerSet each (e.g. a table shipping as 2 cartons: top + legs). All cartons of a set ride in the SAME container. Uses real 3D packing (not just volume math) and reports the binding limit (dimension / weight / volume) per container. Omit `containers` to evaluate the standard 20' DC, 40' DC and 40' HC.
Containers to evaluate. Omit to use the standard catalogue (20' DC, 40' DC, 40' HC).

}Generate a CAD-style PDF + 3D PNG report for a packing job. IMPORTANT: to keep the report consistent with a plan you already produced, pass the `result` object from your previous pack_containers call — the report then renders that exact plan instead of recomputing. Returns base64-encoded PDF + PNG per container.

| pallet | object | The pallet to stack onto. Required when loadingMode is "pallet". |

| container | object | |

| loadingMode | string | 'bulk' (default) loads cartons straight into the container. 'pallet' first stacks cartons onto pallets, then loads the pallets — requires the `pallet` field. |

}Pack a list of cargo SKUs into one or more shipping containers using the Kubova solver. Supports bulk loading (cartons straight into the container) and pallet loading (loadingMode:"pallet" + a pallet — cartons are stacked onto pallets first, then the pallets loaded). Per-SKU you can set allowed orientations, no-overstack/no-understack, and loading order. Returns per-container placements with x,y,z coordinates in cm, volume utilization, weight, a weightBalance object (centre of gravity + front/back & left/right weight split, flags an unbalanced load) for bulk loads, and any unplaced pieces.
