Professional logo design. // SUBJECT Vector logo for a personal running challenge "Decembre 496". The logo is a modern, epic emblem for a social media profile picture. // CORE ELEMENTS The design is focused on a highly stylized and geometric number "496" at the center.

The typography is a clean, strong, sans-serif font like "Montserrat Bold". // STYLE & MOOD The style is ultra-minimalist, epic, and inspiring. It should feel like a prestigious medal or a mission patch. Flat design with extremely clean lines. High contrast and immediate readability. // COLOR PALETTE Strict color palette: a deep navy blue background (#0A192F), with the main elements in crisp white (#FFFFFF) and a single, vibrant electric blue accent (#00A6FB) for the number 496 or a key line. // COMPOSITION Perfectly centered circular composition. Excellent use of negative space to create a sense of importance and clarity. // NEGATIVE PROMPT --no 3d render, shadows, gradients, photorealistic, handwriting, script font, cluttered, messy, complex illustration, signature
