Selected profit density—

Every product's profit density is margin/unit × weekly velocity ÷ shelf-space required. Products are greedily sorted by density (highest first) and given shelf space until the shelf's total capacity is used up — a real fractional-knapsack allocation, recomputed live whenever capacity, margin, velocity or space requirement changes.
