perpetual op• Data kinds: none → rgb (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.perpetual_apollonian(depth: 'int' = 6, size: 'int' = 520) -> 'np.ndarray' (to call the implementation directly, import perpetual; perpetual.perpetual_apollonian(depth: 'int' = 6, size: 'int' = 520) -> 'np.ndarray'; from the registry, opsgenerative.get("perpetual_apollonian"))

アポロニウスの円詰め ―― 隙間に接する円を入れ続ける(終わりが無い)。
不変量: 互いに接する 4 円の曲率が デカルトの円定理
`(Σk)² = 2Σk² を厳密に満たす。:func:perpetual_identities` で確かめられる。
★塗りの明るさは曲率(= 1/半径)。定理が試している量をそのまま色にして
あるので、絵の濃淡が主張と同じものを指している。
