RUNNER

Page URL — The inscription id in the path is hashed into seeds so each inscription looks different (generative art).
/r/inscription/<id> — Inscription number and sat number (Ordinals recursive API), when the host allows it.
/r/sat/<id> — Block height tied to that sat, mixed into seeds.
/r/blockheight — Current chain height as a fallback if sat data is missing.
WebSocket wss://mempool.space/api/v1/ws — Live mempool fee (sat/vB) to pick walk vs run unless you press Space.
3D assets — Character and animations load from inscribed /content/… ids baked into this HTML (no external CDNs).
