Make isometric tiles and buildings from sketches

Make the level 1 Goat Stable with GPT Image 2.5 Sunburst (model_openai-gpt-image-2-5-sunburst). referenceImages as an array: the stable sketch first, the town hall second. Square (1:1), quality "high", background "transparent". Quote the cost with a dry run first and wait for my go.

Prompt, word for word:
Reference 1 is a rough layout sketch: follow its shapes, proportions and placement exactly (a barn on one isometric ground tile, gable roof with the ridge running from front-left to back-right, a big arched double door on the left wall, a round hay-loft window in the right gable, a goat weathervane on the roof ridge, a small fenced pen with a water trough on the right of the tile, two hay bales by the door). Reference 2 is the style anchor of the game: match its chunky stylized 3D look, soft global illumination, tactile materials, warm saturated palette and blue-and-gold accents. Do not copy the building.

Game asset: the Goat Stable, level 1, home of Queen Pip's battle goats, for a mobile strategy game. True 2:1 isometric projection, camera from the front corner, light from the top left. Painted timber walls on a rounded stone base, blue slate roof, gold trim, a blue banner with a small gold crown by the door, a chunky gold goat weathervane, a round hay-loft window stuffed with hay. The building sits on one grass diamond tile with a short cobblestone path to the door, tile edges matching the sketch's tile. Single building, centered, transparent background, no cast shadow outside the tile, no text. Style: chunky stylized 3D at the standard of the world's top mobile strategy studios: thick silhouettes, big heads and hands, soft global illumination, tactile materials (painted wood, brushed steel, felt cloth), warm saturated palette, readable at phone size.

Use the approved level 1 stable's asset ID as the only reference, same settings. Level 2 prompt, word for word:
The reference image is the level 1 Goat Stable of a mobile strategy game. Draw its level 2 upgrade: the same building grown, not replaced. Keep the same 2:1 isometric projection, camera corner, top-left light, scale of doors and windows, chunky stylized 3D look, painted timber walls on a rounded stone base, blue slate roof, gold trim, arched double door, round hay-loft window, blue crown banner and gold goat weathervane. Add a second wing on the right side with a hay loft and a pulley hoist, a taller stone chimney, a larger fenced pen with three goats, and a gold saddle rack by the door. The footprint grows to fill one 2 by 2 block of grass tiles with straight diamond edges. Single building, centered, transparent background, no text.

For the windmill, also with the approved stable as the only reference, open the prompt with this, word for word, then describe the windmill:
The reference image is a building from the same mobile strategy game: match its 2:1 isometric projection, camera corner, top-left light, scale of doors and windows, chunky stylized 3D look and palette. Do not copy the building,

Quote both first and wait for my go.

Make the ground with Scenario Texture (model_scenario-texture): the town hall as the reference so the palette matches, 1024 x 1024, with Erase Seam on (read model_schema_get for its parameter name). One surface per run. Grass prompt, word for word:
Stylized ground texture for a mobile strategy game: short lush grass with small clover patches and a few tiny white and yellow flowers, soft painted shading, warm saturated palette, viewed straight from above, even lighting.

Then, in code, turn each texture into a tile: rotate it 45 degrees, squash it to half height and mask the diamond.

Measure the angle of each footprint's diamond edges against the tiles, and the edge contrast of each texture at the wrap-around against its interior. Tell me which buildings or textures fail and redo only those. Then create a collection for the village block with the buildings and textures, and report the models, every asset ID and the total cost spent.
