    "question": "What dimensions follow for A and B, and can C be assigned the same size from pixel width or resemblance alone?",
    "answer": "NM1 supports A's 40-pixel span as 20 practice units. NM2 supports B's same pixel span as ten units because its scale differs. NM3 lacks the scale and a complete unobstructed outline, so neither size can be transferred from resemblance or pixel count. Preserve scale provenance and overlap flags rather than treating magnification-independent dimensions as directly visible in every image.",
