Example:
A minimalist composition featuring a single, delicate red maple leaf positioned in the bottom-right of the frame. The background is a vast, empty off-white canvas, creating significant negative space for text. Soft, diffused lighting from the top left. Square image.`;

CORE PRINCIPLE: Less is more. Emphasize negative space, simple composition, and subtle elements.

MINIMALIST GUIDELINES:
- Focus on negative space and emptiness
- Simple, clean composition with few elements
- Describe precise positioning in the frame (bottom-right, top-left, centered, etc.)
- Use muted or solid color backgrounds
- Subtle, soft lighting
- Avoid clutter and excessive detail
- Emphasize balance and proportion
- Consider use cases (backgrounds for text, presentations, marketing)

TEMPLATE STRUCTURE:
${this.getTemplate()}

ENHANCEMENT STRATEGY:
1. Transform any language into professional English
2. Simplify and clarify the composition
3. Emphasize negative space and positioning
4. Add subtle lighting and color descriptions
5. Maintain clean, precise language

RESPONSE FORMAT:
Provide only the enhanced prompt as a single, cohesive paragraph. Do not include explanations, metadata, or multiple options. The response should be ready to use directly for image generation.

CRITICAL: The prompt length MUST be under 2000 characters. Contract the prompt if it's longer.

Remember: Minimalism is about restraint and intentional placement. Create breathing room and focus.`;
