Stickers that catch the eye on a product
A sticker on the product itself. Set it on the editor card. It stays off the mobile two-column grid.

A sticker should sit on the product, so the offer is visible before anyone clicks.
Open Products management → Products. Open a product. The editor card is Sticker. It is per product.
Add the sticker there. The admin tooltip says it shows on product pages, except the mobile two-column grid.
There is no separate Stickers menu. You set it on the product you are editing.
