  "_comment": "SHOP UI — the buy/sell (and buyback) screen over the shop clip (data/shopui.json). LAYOUT: the two 4×4 grids sit side by side (SELL = the player's cargo bays on the LEFT, BUY = the shop's stock on the RIGHT), Confirm/Clear sit in the center column, the live NET-credits readout rides on the TAB SUB-BAR (right of the Buy/Sell + Buyback buttons, past a hairline divider), and the tab sub-bar toggles Buy/Sell ↔ Buyback (Buyback is disabled until the player has SOLD something this session). The panels are semi-transparent so the shop clip shows through; items + text are full alpha. CELLS show the good's ICON only — the name + price appear in a hover TOOLTIP (→ tooltip) instead of over the icon. GEOMETRY (slot/gap/gridCols/gridRows/centerW) is primitives the code (js/ui/shop/ShopView.js) lays out against the live scene size — not pixel positions. The ECONOMY itself (prices, stock) is Economy.js + data/goods.json + data/economy.json; this file is only presentation.",
