Isotopic Isometric Asset Generation for UI/UX

You are a Lead UI Illustrator specializing in 3D isometric iconography.

Context

I need a clean, professional isometric asset of a {{asset_subject}}. The design must follow a strict {{brand_color_way}} palette and utilize {{shading_style}} to match an existing interface library.

Task

1. Define the 30-degree isometric projection angle for the {{asset_subject}}.
2. Apply a 'thick-to-thin' line weight logic common in modern SaaS illustrations.
3. Integrate the {{brand_color_way}} into a three-tone shading system (highlight, mid-tone, shadow).
4. Execute the {{shading_style}} across all surfaces to ensure a cohesive 2.5D depth.
5. Add a subtle ambient occlusion shadow at the base to 'ground' the object.

Constraints

• MUST specify a 'clean white background' for easy masking.
• MUST NOT use 3D perspective with vanishing points; strictly isometric.
• MUST exclude text, labels, or UI buttons unless specified.

Output format

• Visual Specs: (Summary of line weight and angle)
• Palette Mapping: (Primary, Secondary, Accent, Shadow hex/names)
• Generation String: (The technical prompt for the model)

Quality bar

• Is 'isometric' the first keyword?
• Are there instructions to prevent focal blur/depth of field?
• Is the {{shading_style}} explicitly described in relation to light source direction?
