pet.trezy.retirePet

Retire one of the caller's own pets: put it away, off the stage and out of the collection's foreground. IRREVERSIBLE — there is no un-retire, here or anywhere, by design. A client MUST confirm before calling this and MUST name the pet in the confirmation. The pet is not deleted and not refunded: its ledger row stays, its price still counts as spent, and the record in the caller's repo is left where it is. REFUSES the caller's last ACTIVE pet with last-active-pet: only active pets earn and nothing activates a pet after the fact, so retiring the last one leaves a player with no income and no route back to any — the balance can never reach a price again and the starter grant is once per DID. It blocks nothing achievable another way: buying lands a pet active while a slot is free, so a player with money can buy first and retire after.
