Photopea: prepared synthetic Remove BG pilot

This archive contains two existing 512 x 512 synthetic geometric product inputs,
eight fixed evaluator-only masks and the unchanged frozen v2 contract.
The creator background and official workflow are documented on the product profile.
No input has been imported into Photopea, no Remove BG call has been made,
and no output PNG or product score is available at archive preparation.

inputs/: only these two PNGs may be supplied to the editor after authorization.
references/: evaluator-only masks; do not upload them to the product.
frozen-photopea-contract-v2.json: complete case wording, all 12 acceptance
conditions, fixed masks/regions and metric definitions, output names and scope.

For each case, use native File > Open, Select > Remove BG, then File > Export As
> PNG and Save. Retain the first unchanged native export at 512 x 512.
Maximum one native removal per case; do not repair, resize, change models or
rerun to improve quality. Preserve any gate, failure or unknown result.
No payment, upgrade, API key or new supplementary terms are authorized here.
Specific input-import and free AI-use authorization is pending.

The synthetic fixtures do not measure natural photography, broad marketing
suitability, a hidden model identity, autonomy or cloud privacy. This pilot
does not rerun Rembg or read its output or metrics. Input and reference PNG
bytes are copied unchanged from the earlier public synthetic fixture.
