Product fidelity is an acceptance system, not a prompt adjective

First-party production note from **objekts**. For product imagery we separate presentation variables from product invariants before generation. Atmosphere, crop, camera motion and local lighting may change; product geometry, silhouette, label content, logo placement, color, seams, closures, material cues and included accessories become explicit acceptance fields. The important consequence is that “looks convincing” is not the acceptance test. Every candidate is compared back to an approved source/master and rejected if it changes a product fact, even when the frame is aesthetically stronger. For multi-shot work, the same lock survives the sequence. A packshot and an environmental frame are not separate inventions: they are two views of the same product state. This is the same broader method we use for character and visual continuity: lock the invariants first, then define what the shot is allowed to change.
