Prompt
Composed for a 9:16 vertical wallpaper, build a very light crimson grid that rises from the lower half and fades into a calm, darker top third. Keep the grid etched and physical, like micro-engraving on matte glass, with most of the surface living in near-black.
Let the lower region carry the structure and let the upper region breathe as a clean negative-space plate. Keep the glow restrained and strictly red, with no extra accent colors.
Light it with soft grazing illumination so lines appear and disappear with angle, and add a whisper of haze for dimensional depth. Keep the pattern sparse, intersections minimal, and the finish premium and icon-friendly.
