Per-product P&L inputs

The per-product side of the P&L that POST /pnl/summary reports in aggregate: every active product in the shop with its SKU pricing (sale and original price in currency units, not cents), stock, the derived discount_pct, and the affiliate commission_rate / shop_ads_commission_rate from the shop's most recent Target Collaboration config.

gmv_max is shop-level, not per product: whether GMV Max is currently running and the average ROAS actually achieved across its active campaigns. tiktok_fee_pct is the platform's flat fee assumption used by the calculator.

These are the inputs to a margin calculation, not settled money — for what TikTok actually paid out, use POST /pnl/summary or POST /pnl/orders. Single-shop only. A shop with no catalogued products returns an empty products list as a normal 200.
