Fix a bad generation with a surgical edit

Inpaint only the masked region. Everything outside the mask must remain byte-identical.

In the masked area, render: {{exactly what should be there}}. Match the surrounding image on all of these: light direction and hardness, colour temperature, grain amount and size, focus and depth of field at that distance, perspective, and material texture. The new content must continue any lines, edges, or patterns that cross the mask boundary without a visible seam.

Do not add anything not described. Do not alter the subject's proportions or expression. Do not brighten or sharpen the region relative to its surroundings.

Negative: seams, mismatched grain, sharper-than-surroundings detail, duplicated features, extra fingers, text, watermark.
