loop op• Data kinds: rgbvideo → table
• Call: import fullseye as fs; fs.ledger.perpetual_loop_seam(video: 'np.ndarray') -> 'dict' (to call the implementation directly, import perpetual; perpetual.perpetual_loop_seam(video: 'np.ndarray') -> 'dict'; from the registry, opsgenerative.get("perpetual_loop_seam"))

循環動画の継ぎ目を数で出す(`table`)。
`seam = 最終コマ → 初コマの差、typical` = コマ間の差の中央値。
継ぎ目の無い動画では `ratio = seam / typical` が 1 に近い(最後の
またぎが、ほかのまたぎと見分けが付かない)。0 ではなく 1 が正解なのが
ここの読みどころ —— 0 は「動きが止まっている」という意味になる。
