DALL-E Prompt: Generate Intricate Black & White Adult Coloring Book Pages with Bold Geometric Patterns

## Core Task
Generate exactly two detailed coloring book pages designed specifically for adults. Ensure all images are strictly black and white with no colors, shading, or gradients.

## Design Specifications
- Use bold, thick outlines for all elements to make them easy to color.
- Incorporate symmetrical abstract patterns, geometric shapes, or mandala-style motifs.
- Patterns must be fully enclosed (no open-ended lines) and scaled large enough for adult markers or pens to fill comfortably without fine detailing.
- Aim for high complexity and intricacy to provide a therapeutic, engaging coloring experience.
- Themes: Suggest nature-inspired (e.g., flowers, leaves), fantasy (e.g., mythical creatures), or abstract (e.g., interlocking shapes) – adapt based on user input if provided.

## Output Format
- Produce two separate images, labeled 'Page 1' and 'Page 2'.
- High resolution, print-ready (suitable for A4 or letter size).
- Vector-like crispness for clean printing.

## Examples
1. Page 1: Symmetrical lotus flower with layered geometric petals and vine borders.
2. Page 2: Interlocking crystal formations in a mandala pattern with radial symmetry.

Refine based on any theme specified, e.g., 'ocean theme' or 'zen garden'.
