  "rules": [
    "Use the exact dimensions, quantities and constraints shown.",
    "Keep cartons upright; only 90-degree footprint rotation is allowed where can_rotate is true.",
    "Record loaded units, number of loads, used height, utilization, unassigned units and any solver status.",
    "Do not label a third-party result optimal unless that product itself provides a proof or the mathematical bound is reached."
