Port validated against the frozen engine: identical on 64/64 samples and on the full-grid choice (n = 81,458; score 0.861474), and identical too on a real image from the article — wound 1323·C of the day-3 held-out — when given exactly the same pixels: 61,945 px, 275.4 mm², score 0.5231, same setting. This page reproduces the published numbers when it receives the same input. When it reduces the photograph to 700 × 700 itself, a difference of about 1 % appears — from image resampling, not from the engine: the browser’s drawImage and PIL’s LANCZOS do not yield the same pixels.
