  "result": "I've written `out/scene.html`: a glowing jack-o'-lantern under a crescent moon and stars, on a 640\u00d7400 canvas titled \"Jack-o'-lantern 196\". I couldn't run the full set of checks because Playwright isn't installed here. I only took one screenshot with headless Chrome. It drew the scene correctly, and the four page corners and the top centre came out pure black (0,0,0).\n\n**How it's built:**\n- **Flame:** each animation frame works out a new brightness from a few overlapping waves plus some randomness, kept between 0 and 1. It should swing roughly from 0.2 to 1.0, well over the 0.15 range the check needs.\n- **Pumpkin:** centred at (320, 270) with radius 90. The glow, the carved face and the body colour all brighten and dim with the flame, so the area inside the pumpkin changes from frame to frame.\n- **Night:** the page background is black. Stars are kept out of the corners and away from the top centre, and the moon is placed clear of them too.\n- **Self-contained:** the file is about 5 KB, links to nothing outside itself and makes no network requests. Calling `window.sceneState()` gives `{flame, pumpkin: {x, y, r}}` based on what is currently drawn.\n\n**Not verified:**\n- Whether the 30 flame samples over 3 seconds give at least 6 distinct values and enough spread. This is expected from the code, but I didn't measure it.\n- Whether the browser console logs any errors. Chrome's log output showed nothing, but that isn't the same as the scorer's error check.",
