illusion 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.illusion_muller_lyer(length: 'float' = 220.0, head: 'float' = 34.0, angle_deg: 'float' = 35.0) -> 'np.ndarray' (to call the implementation directly, import illusion; illusion.illusion_muller_lyer(length: 'float' = 220.0, head: 'float' = 34.0, angle_deg: 'float' = 35.0) -> 'np.ndarray'; from the registry, opsgenerative.get("illusion_muller_lyer"))

不変量: どちらの軸も長さ `length`(浮動小数の同一値)。
• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).
• Operator provenance and references — the sources of the research/methods this op family came from.
• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
