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_reaction_diffusion(size: 'int' = 220, steps: 'int' = 1600, feed: 'float' = 0.037, kill: 'float' = 0.06, seed: 'int' = 0) -> 'np.ndarray' (to call the implementation directly, import perpetual; perpetual.perpetual_reaction_diffusion(size: 'int' = 220, steps: 'int' = 1600, feed: 'float' = 0.037, kill: 'float' = 0.06, seed: 'int' = 0) -> 'np.ndarray'; from the registry, opsgenerative.get("perpetual_reaction_diffusion"))

グレイ–スコット反応拡散 ―― 模様が生まれ、分裂し、増え続ける。
不変量: **餌も死も 0(`feed = kill = 0`)なら、総量は厳密に保存される**
—— 拡散は再分配であって生成ではないから。数値解法が壊れていれば、
ここが真っ先に崩れる(:func:perpetual_identities)。
• 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.
