    "answer": "SFZ1's scale gives A a width of 30 practice units: 60 pixels times ten units per 20 pixels. SFZ2 lacks a scale and is earlier despite its file order, so its larger pixel span does not establish growth or a physical size difference. SFZ3 belongs to B and cannot supply A's firmness. Report the supported width and missing A-specific firmness evidence without deciding harvest or handling readiness.",
