- TradeGrid cells now render only the good's icon; hovering a usable cell reveals a shared per-grid tooltip with the name and "sell/buy for N cr" price line, anchored above (or below on the top row) and clamped to the panel.
- Per-cell name/price text objects are removed; a single `label` remains only for locked/empty state ("locked", "—").
- data/shopui.json: add `tooltip` section (bg, border, pad, gap, font sizes) and bump `iconScale` to 0.62 so icons fill the now-cleaner cell.
- Apply theme fonts throughout the shop UI — Ethnocentric for section titles, Centauri for body text, tooltip, stepper, and buttons via `fontStack()`.
- dev/shop-shot.mjs: replace old layout probe with a hover-tooltip probe (structure check, programmatic + real mousemove hovers on sell/buy cells, pointerout hide) and await web fonts before boot so screenshots use the real typefaces.
- dev/shop-ui.test.mjs: new HOVER TOOLTIP suite asserting tooltip visibility, text content, locked/empty suppression, unhover, buy-side pricing, and theme font application.
