Edit my attached portrait for [background/light/framing]. Preserve
my source facial proportions, expression, hairline, visible grey hair,
lines, skin detail, clothes and pose. No rejuvenation, beauty makeover,
face slimming, new smile or age-based redesign. Use the original as
the appearance authority. If a detail is not readable, do not invent
it. Return one candidate for comparison with my untouched source.

---

The new background is useful, but the candidate changed [visible
source feature]. Return to my untouched original. Restore that
feature and the source facial shape while keeping the useful light
and background. Do not infer an ideal age or add generic wrinkles.
Keep the source expression, hair and clothing. Return one candidate
for the depicted person to inspect before use.
