A bare wand lights a single charge

'ANY CARD MAY BE PLAYED WITHOUT A NUMBER CARD, but its power is only 1.'
The wand first-use gate was the engine's one remaining missing-number
refusal — everything else already defaults its power to 1. A wand cast
bare now charges to one, fires once, and crumbles; the client hint says
so. Ungated: the refused casts never reached a ledger.
