pub const REPOS_UNPLACED: u8 = 0xFF;Expand description
The inventory-grid position an item that has never been placed holds.
Repos_PosX and Repos_Posy are BYTEs read only by the nested container
path, and both default to 0xFF rather than to a plain zero. Grid slot 0
is a real slot, so a zero fallback places every unplaced item in the
top-left corner.
