  "result": "I wrote `out/scene.html`, a single 2.5 KB file. I haven't opened it in a browser. What I did test: I pulled the firing-curve code out of the file and ran it in Node at several timestamps, and the temperatures and statuses matched the spec for all three kilns.\n\n| Time | Kiln 1 and Kiln 2 | Kiln 3 |\n|---|---|---|\n| 0.5 s | 22 \u00b0C, waiting | 322 \u00b0C, heating |\n| 1.7 s | 322 \u00b0C, heating | 1220 \u00b0C, holding |\n| 2.5 s | 802 \u00b0C, heating | 618 \u00b0C, cooling |\n| 3.0 s | 1000 \u00b0C, holding | 22 \u00b0C, cooled |\n| 4.0 s | 330 \u00b0C, cooling | 22 \u00b0C, cooled |\n\nHow it meets the contract:\n- **Stage:** a 760\u00d7500 `<canvas>` with the title \"Pottery Studio Kilns 659\". The spec values are copied into the file, so it needs nothing else at runtime and makes no network requests.\n- **Drawing:** each animation frame draws every kiln at its spec `x`, with a glowing chamber, a red temperature bar of `px_per_100c` pixels per 100 \u00b0C, a label, and a running clock. The clock changes every frame, so the screenshots should differ.\n- **`window.sceneState()`:** it works out each kiln's temperature and status from `performance.now()` at the moment it is called. The drawing uses the same function, so the reported state matches what is on screen. The curve is the one in the spec: room temperature, a straight rise from `room_c`, the hold at peak, a straight fall, then room temperature again.\n- **Self-contained:** the file contains no URLs. I didn't run a console check in a browser; the script uses only plain canvas calls.",
