🌓 Before/After Proof Pack

Before/After Proof Pack turns a real product improvement into credible visual evidence. Supply the original before and after screenshots, the proposed claim, supporting evidence, and target marketplace dimensions. It checks whether the pair shows the same product, content, state, viewport, and crop; normalizes the presentation without altering the underlying result; maps annotations to observable changes; and flags claims the supplied evidence does not support. The output includes normalized pairs, comparison layouts, marketplace thumbnail and gallery specifications, truthful captions and alt text, and unsupported-claim warnings. It does not invent results, replace screenshots with synthetic product states, or turn aesthetic preference into a measured commercial claim.
