 "title": "Pagoda City: MiMo-V2.6-Flash-RL, thinking on vs thinking off",
 "date": "2026-09-27",
 "prompt": "Create a single self-contained HTML file using Three.js (load it from a CDN via an import map) that renders an interactive voxel world: a tall multi-tiered pagoda standing on a mountainside, with a voxel city spread around and below it — houses with sloped roofs, narrow streets, stairways climbing the slope, a river or waterfall coming down the mountain, bridges, trees, and lanterns. Everything is built from cubes (voxels); no imported models or textures.\n\nRequirements:\n- Terrain: procedurally generated voxel mountains with the pagoda on a prominent ridge and the city terraced down the slope toward a valley. Use at least 3 distinct height bands (snow / rock / grass) with color variation so it doesn't look flat.\n- The pagoda must have at least 5 tiers with upturned eaves, a spire, and lit windows.\n- Rendering must be efficient: use InstancedMesh (or merged geometry) so tens of thousands of voxels render at 60 fps on a laptop GPU. Add shadows from a directional sun and a soft sky/ambient light.\n- On load, the camera performs a slow cinematic orbit around the pagoda and city for the first 10 seconds, then hands off to the user.\n- Interactivity (all must work):\n  1. Orbit / zoom / pan camera with mouse (OrbitControls), starting from a cinematic view of the pagoda.\n  2. A day/night slider or button that moves the sun, shifts the sky color, and turns on the pagoda and city lanterns at night (emissive voxels, and a few point lights near the pagoda). Lanterns should switch on in a visible sequence, not all at once.\n  3. Clicking on any voxel of the city or pagoda highlights it and shows a small tooltip with what it is (e.g. \"Pagoda tier 3\", \"House roof\", \"Bridge\") — use raycasting against the instanced meshes.\n  4. A \"regenerate\" button that rebuilds the terrain and city from a new random seed without reloading the page.\n- Add subtle ambient animation: drifting clouds (voxel clouds), flickering lantern light at night, and a slow water animation on the river.\n- Include a small on-screen legend/help panel describing the controls, and an FPS counter.\n- The page must load with no console errors, must not rely on any files other than Three.js from the CDN, and must not use any deprecated Three.js APIs (r160+).\n\nReturn only the complete HTML file in a single code block.\n",
