HOUSE, DAY  ->  src/assets/render/house.webp (1640 x 916, transparent around the house)
Input: your reference (a straight-on street-front render from a free 3D model, or a photo of your house).
Image-to-image strength / denoise 0.45-0.6 (keep the geometry), or "edit this image" in a chat image tool.

Redraw this exact house as an architect's alcohol-marker presentation rendering. Keep the identical composition,
camera, framing and proportions: every element stays exactly where it is in the reference - {the storeys, the roof
and what covers it, the facade materials, every window and door, the garage, the front garden and its trees, the
front wall, the steps and the pavement}. {MARKER STYLE - Exterior}
Leave the whole sky as blank white paper: no sky colour, no clouds, no sun, no birds. The ground and pavement fade out
into the white paper at the bottom and sides with loose hatched marker strokes.

Then: python3 tools/pictools.py cutout house-day.png src/assets/render/house.webp --size 1640x916 \
        --night src/assets/render/house-night.webp
(The sky must stay plain paper: the cut-out keys on it. The app paints its own sky, sun, clouds and weather.)
