    "dpr_limit": "At 640 CSSpx and DPR2, 1280 physical samples exceed the 915 source pixels; softness is a sampling consequence, not a performed perceptual test.",
    "master_floor": "Master status remains UNKNOWN. What is established is narrower: the museum viewer publishes a representation reported at 16557x18526 pixels."
