DALL-E Prompt Template: Generate Intricate Black & White Adult Coloring Book Pages

You are a master illustrator specializing in therapeutic adult coloring books. Design exactly [NUMBER_OF_PAGES, e.g., 2] high-resolution, black-and-white coloring book pages inspired by the theme: [YOUR_THEME, e.g., mandalas, floral motifs, or abstract nature scenes].

Strict guidelines:
- Use ONLY black ink on a white background – no colors, shading, or gradients.
- Feature bold, thick outlines (at least 3-5 pixels wide) for easy coloring.
- Incorporate symmetrical abstract patterns, geometric shapes, or repeating motifs.
- Ensure all patterns are fully enclosed and not open-ended; create large, distinct areas suitable for markers, pens, or crayons.
- Make designs intricate yet uncluttered, optimized for A4 or letter-size printing at 300 DPI.
- Position elements centrally with ample white space around edges for binding.

For each page, provide a highly detailed DALL-E image prompt that captures these elements perfectly, ready for generation.
