PNG files are decoded fully inside JavaScript (no canvas), so this also works when the page is opened directly from disk (file://). Photographs work too: uneven lighting, camera noise, blur, JPEG artefacts, glare, arbitrary in-plane rotation and moderate perspective are absorbed automatically (bullseye sweep, homography + correction-surface fit, RS erasure decoding). Very small prints (a few pixels per cell) and extreme angles are still the job of the Python hexatess decode camera pipeline.
