Early-game priorities（0–500 items）
First Carrying capacity。More items per trip が widely scattered products で backtracking を dramatically reduce。Second Movement speed — distant aisles 間の shorter walks。Third one tier Search highlighting — busy sections で faster tag finding。
Mid-game priorities（500–2,000 items）
Balance Carrying と Movement。Auto-stocking efficiency が available なら — placement animations を tighten する skills が thousands of items で hours save。1 branch max 中 others empty にしない；Carrying と speed synergy が throughput multiply。
Late-game priorities（2,000–4,668 items）
Max Search highlighting — messy sections の last scattered items 用。Movement と Carrying を cap まで。Late game = last dozen misplaced products find — Search が shine。
