Deep Space Nebula Dust Filament Clustered along Mobile Lower Boundary

Full prompt

A cinematic cosmic digital illustration depicting an otherworldly emission nebula nestled inside deep space. Glowing filaments of interstellar hydrogen gas in copper, violet, and deep cyan glow softly across the bottom third of the vertical canvas, harboring miniature clusters of nascent stars and cosmic dust rifts. The upper two-thirds shifts into deep velvet obsidian space sprinkled with sparse, microscopic distant galaxies and faint stellar points, ensuring zero visual noise in the smartphone status and widget zone. Rendered with volumetric raymarching to achieve realistic light falloff and celestial depth with a tranquil, contemplative mood.
