A professional, minimalist brand logo mockup for "Numb.", presented on a detailed, raw textured gray concrete surface, inspired by image_228.png. The central focus is the text "Numb." in a bold, clean Swiss typography (like Akzidenz-Grotesk or Helvetica Neue), deeply engraved into the concrete. The letters have precise, sharp, machine-cut edges, catching cold, directional industrial lighting from the left, which casts subtle, defined shadows into the engraving, emphasizing the depth and raw feel of the material. Below the main name, in a slightly smaller, precise condensed font, the word "BRUTALIST CASE." is also engraved. The entire presentation is heavy, silent, and technical. The concrete shows varied grain and tiny aggregate. Cinematic macro-focus, high detail, 8k, desaturated color palette (grays and deep shadows). The "Star" icon is subtly integrated, perhaps etched directly into the concrete below the text. Minimalist composition.
