Large impostor cards can replace triangle work with substantial empty-pixel processing. Do not assume that the representation with the fewest vertices wins.\n\nRecord measured frame cost alongside visual acceptance and storage. Keep collision, gameplay identity, and rendering representation coordinated without requiring identical geometry.
