furnish the Poke Marts to the finished interiors' standard

The MART tileset shares the Center's atlas but not its pins, so marts
were raw detector output: 32px walls, the racks fused into one deep
monolith, the clerk booth a 48px slab. Pinned like the references --
16px wall band with the built-in cases, bookcase-collapsed racks,
half-cell counter with the poster on top, register standing on it.
