Create one original black-and-white brand logo presentation.

Create one original black-and-white brand logo presentation. Brand name: [Brand Name] Subtitle: [Short Subtitle] Category: [Brand Category] Mood: [Mood] Design a clean white logo on a pure black background. Include a custom icon + wordmark system. The logo should feel like a professional designer portfolio piece: minimal, sharp, readable, high-contrast, brand-ready. Use subtle gray portfolio details if needed, such as thin divider lines, “BRAND LOGO — 2026”, a small registration mark, or a tiny corner signature. Avoid colorful elements, poster style, 3D, mockups, complex illustration, mascot, messy layout, generic fonts, and multiple logos in one image.
