Image generation prompt builder

I want to generate an image of: {{subject}}. Style: {{style}}. Use case: {{use_case}}.

Write a prompt optimized for {{tool}} (e.g. Midjourney, DALL-E, Ideogram, Flux). Include: subject description, composition/framing, lighting, color palette, art style references, and any technical parameters the tool supports. Then write 2 variations: one more photorealistic, one more stylized. End with 3 negative prompts to avoid common failure modes.
