Premium black and white optical logo built from light structure

Create a premium black-and-white optical logo for a fictional brand. Use a pure black background, white/gray logo elements, and a clear icon + wordmark system. The logo should use light as structure: slit projection, masked reveal, prism planes, particle grid, negative space, or partial illumination. Make the mark strong, readable, high-contrast, and logo-like. Use bold custom typography, clean geometry, sharp light edges, controlled shadow falloff, and enough black negative space around the logo. Avoid real brand names, copied logos, watermarks, copyright marks, TM, extra tiny text, lamp icons, bulb icons, sun/moon icons, neon colors, rainbow prism effects, realistic scenes, and poster-style layouts. Brand examples: SLITRA / VEILUX / PRISVA / DOTLUME
