Groundworks

Players

• A sheet holding a Blueprint is told from paper: it is named Blueprint, glints, and its tooltip says Copy or Cut, how many blocks it holds and the box's size, and "Pasting air" when set to. A blank sheet with a Corner stored says where. A sheet stamped by an earlier version catches up the first time it is held. An anvil's name shows over Blueprint, and goes nowhere. (#87)

Consumers

• A sheet holding a Blueprint carries the new groundworks:blueprint_summary component beside its id, and vanilla's item_name and enchantment_glint_override, all reset when it is blank again. (#87)
