Make key art and every format from one master

Make the key art master with GPT Image 2.5 Sunburst (model_openai-gpt-image-2-5-sunburst): referenceImages [Zuri's hero, Zuri's turnaround, Marlow's hero, the world key art] in that order, width 2048, height 1152, quality "high", numOutputs 2. Quote the cost with a dry run first and wait for my go.

Prompt, word for word, the cast block first:
Two characters in one scene. References 1 and 2 are ZURI (identity and turnaround): 22, slim, warm brown skin, long box braids tied high with glowing cyan tips, silver hoop earrings, cropped magenta bomber jacket with cyan piping and a white chevron on her right sleeve, black athletic top, fingerless black gloves, charcoal tech leggings, white knee guards, two white pulse blasters holstered on her thighs, roller blades with glowing cyan wheels. Reference 3 is MARLOW: 50, tall and lean, a head taller than Zuri, weathered tanned skin, short grey stubble beard, wide-brimmed sand hat with brass goggles on the brim, faded red bandana, long patched sand duster over a dark brown vest and cream shirt, leather bandolier and belts, olive cargo trousers, brown lace-up boots, a rail rifle with a cyan coil slung on his back. Do not mix their features or clothes. Render both in the stylized 3D game art style of reference 1.

Reference 4 is for the WORLD ONLY: floating salvage islands above a sea of clouds, its palette and its light. Ignore its characters and its logo. Key art for a stylized hero shooter. Zuri skates down a steep twisted hull-plate ramp toward the camera, low and fast, her two pulse blasters drawn, one in each hand, so both thigh holsters are empty, sparks flying from her wheels, big grin; Marlow stands on a rusted girder behind her, rail rifle raised to his shoulder, aiming past her, his coat flaring in the wind. Floating salvage islands above a sea of clouds at golden hour behind them. Composition for a game cover: both characters in the right half of the frame, the left third is calm open sky with soft clouds and no important detail, so a title can sit there. Keep 10 percent of empty margin at every edge so the image can be cropped to other formats. No text, no logo, no letters.

Check each take before you show it: what each character holds, both characters in the right half, the left third open sky, 10 percent margin at every edge.

Extend the approved master with Reframe (model_scenario-gemini-reframe). Quote the cost with a dry run first and wait for my go.

21:9: image the master, aspectRatio "21:9", resolution "2K", position "center-right". Prompt, word for word:
Extend the scene to the left and right in the same stylized 3D game art style: more open golden sky and soft clouds with distant floating salvage islands on the left, more of the rusted girders and hull-plate ramp on the right. Do not change the two characters.

2:3: image the master, aspectRatio "2:3", crop box xStart 640, yStart 0, xEnd 2048, yEnd 1152. Prompt, word for word:
Extend the scene above and below in the same stylized 3D game art style: open golden sky with soft clouds above, continuing smoothly from the existing sky with no visible line, and below, the same rusted hull-plate ramp continuing down at the same scale, perspective and softness, with no visible line. Do not change the two characters. Absolutely no text, no title, no letters, no logo, no labels, no signs, no writing on banners or crates.

Banner: on the 21:9 result, aspectRatio "21:9", resizedWidth 2409, resizedHeight 1022, position "center", with a prompt asking for more sky, islands and girders on every side and the same no-text rule.

Now the approved ad master, with Reframe (model_scenario-gemini-reframe). Quote the cost with a dry run first and wait for my go.

4:5 and 1:1: resolution "2K", crop bounds xStart 250, yStart 0, xEnd 1700, yEnd 1152, position "center". Prompt, word for word:
Extend the dark blue-hour sky above and the wet running track with its reflections below. Keep the runner, her shoes, the floodlight and the water spray exactly as they are. No new people, no reflections of the runner, no text.

21:9: the full master, aspectRatio "21:9". Prompt, word for word:
Extend the wet running track and the dark stadium with its floodlights to the left and to the right. Keep the runner, her shoes and the water spray exactly as they are. No new people, no text.

9:16: from the finished 4:5, positioned at the bottom (read model_schema_get for the value), so the model only adds sky. Two runs. Prompt, word for word:
Continue only the dark blue stormy night sky upward with soft clouds and light rain. No new floodlights, no stadium structures, no people, no reflections, no text.

Download every result. In code, paste the ad master's own pixels back over each extension, feathered about 40 px at the joins, and check the alignment with a difference image. Then crop and resize every format to its exact delivery size, the link preview as a plain crop of the master. Set no title or copy in any generated image. Check the wordmark at 1:1 and each format at its display size, and tell me what fails.

Create a collection for the key art and one for the ad formats, with every final in its own. Report the models, every asset ID with its format, and the total cost spent.
