Label bar in the magnifier tray: seller's claims per label, point out, edit with a labeler

Six labels (model, fan, contacts, bracket, back print, sticker). Dealers
state claims (honest tell the truth, middlemen hide 70%, scammers hide
everything and name the stamped model); the price follows claims until a
label is pointed out, then follows the real state. Pointing at a fake's
evidence exposes the model label too. A wrong accusation costs reputation.
Owned cards can have claims edited freely with a labeler present; a buyer
spots each hidden flaw with 35% chance, which exposes it and costs
reputation. Dimensions are additive percent adjustments on the model price.
