scoop op• Data kinds: scalar × scalar → table
• Call: import fullseye as fs; fs.ledger.spoon_bowl_volume(a: 'float', h: 'float', *, fill_depth: 'float | None' = None, phi_deg: 'float | None' = None) -> 'dict' (to call the implementation directly, import scoop; scoop.spoon_bowl_volume(a: 'float', h: 'float', *, fill_depth: 'float | None' = None, phi_deg: 'float | None' = None) -> 'dict'; from the registry, opsdrive.get("spoon_bowl_volume"))

球冠の椀(縁の半径 `a、深さ h`)の閉形式 —— すり切り・途中まで・山盛り。
球の半径 `R = (a² + h²) / (2h)、すり切り V_struck = π h (3a² + h²) / 6。fill_depth = y` を与えると底から
`y まで平らに満たした体積 V_fill = π y² (3R − y) / 3(y = h で V_struck` に一致する恒等式)。
`phi_deg を与えると縁を底面とする安息角 φ の円錐(山盛りの上限)V_heap = (π/3) a³ tan φ、高さ a tan φ`、
`V_heaped = V_struck + V_heap`、山盛り / すり切りの比。
返り: `R, V_struck, V_fill(与えたとき)、V_heap / H_heap / V_heaped / heaped_ratio`(φ を与えたとき)。
Raises `ValueError: a・h が ≤ 0、h > a`(半球より深い椀は縁が最も広い所でなく、側面から上だけを
見る :func:scoop_volume_read の前提が崩れる)、`fill_depth が (0, h]` の外、φ が (0, 90) の外。
