geometry op• Data kinds: primitive → primitive
• Call: import fullseye as fs; fs.ledger.intersect_planes(p1, n1, p2, n2) (to call the implementation directly, import match3d; match3d.intersect_planes(p1, n1, p2, n2); from the registry, ops3d.get("intersect_planes"))
Plane ∩ plane → a line (a point on it and a direction). None when they are parallel.

方向 `d = n̂1 × n̂2 を単位化し、n̂1·p = n̂1·p1、n̂2·p = n̂2·p2、d·p = 0` の 3×3 を
解いて通過点 `p を求める(d·p = 0 なので **原点に最も近い点**)。返り値 (p(3,), d(3,))`。
`|n1 × n2| < 1e-9`(平行・同一面)なら None。
引数は数値 3 ベクトル(`np.cross` と 3×3 の solve を使うので 3-D 専用。2-D を渡すと
配列構築で失敗する)。次元の混在は ValueError。
用途: `fit_plane_3d した 2 面の稜線、箱のエッジの抽出 → distance_point_line` でエッジ
からの距離。
