- Split each row into a title line (name, "N left"/"SOLD OUT" strip, price,
stepper with `stock.gap` padding between blocks) and a full-width desc line.
- Add `buyList.stock` config (w, gap, fontSize, color) for the inventory strip
and use it for sizing/truncation so the name never collides with the strip.
- Update `_btnXs`, `_nameMaxW`, `_descMaxW` layout helpers to place the right
block on the title line and give line 2 the row's full text width.
- Refresh shop-ui tests to assert title-line padding, truncation budget, and
desc wrap within the full row width.
