Design a minimalist graffiti-style logo for ‘SABU’ with bold, white, geometric text on a solid red background. The letters should appear in the following order: 1. S, 2. A, 3. B, 4. U. Each letter should have a sharp, angular, and aggressive look, using clean, geometric shapes while maintaining the raw energy of graffiti. The design should feel powerful and rebellious, with strong contrast between the white lettering and the vibrant red background. Keep the overall style simple yet impactful.
