Create [specific output] for [actual use] using these permitted inputs.
[Source file] controls the subject and its defining visible details.
[Treatment reference] supplies only [light/material/colour properties].
[Layout reference, if supplied] controls [placement/crop/text region].
Exclude the treatment reference's subject, pose, clothes, props, wording
and composition unless explicitly authorised above. Keep source facts
and person/product geometry separate from treatment. Return one candidate
and identify any instruction that the available inputs cannot support.

---

The requested [treatment property] is useful, but the candidate copied
[unwanted reference element]. Return to the source for subject authority.
Remove that copied element and keep only [allowed treatment cue].
Preserve source geometry, factual content and the actual layout boundary.
Return one file for another role-by-role comparison; do not claim
that the reference roles were followed without inspecting the result.
