tactorque op• Data kinds: matrix × matrix × scalar × scalar → matrix
• Call: import fullseye as fs; fs.ledger.punch_pressure(X, Y, a: 'float', P: 'float' = 0.0, M1=(0.0, 0.0), pitch: 'float | None' = None, sub: 'int' = 4) -> 'np.ndarray' (to call the implementation directly, import tactorque; tactorque.punch_pressure(X, Y, a: 'float', P: 'float' = 0.0, M1=(0.0, 0.0), pitch: 'float | None' = None, sub: 'int' = 4) -> 'np.ndarray'; from the registry, opsdrive.get("punch_pressure"))

平頭円形押し込み子(半径 a [m])の圧力 [Pa]: p = P/(2πa√(a²−r²)) + 3(M1_x x + M1_y y)/(2πa³√(a²−r²))(r < a、外は 0)。
第 1 項 = Johnson 1985 式 3.34、第 2 項 = ∫ (x, y) p dA = M1 を満たす反対称項(導出はモジュール docstring、門で数値確認)。
`pitch` を渡すと画素を sub×sub の副標本で平均する(縁の 1/√ 特異点の格子誤差を減らす。4×4 で Σ p h² が P と 0.6 %、実測)。
Raises ValueError: a ≤ 0、P < 0、X と Y の形が違う、|M1| > Pa/3(接触が離れる: 線形の式が成り立たない、fail-closed)。
