Deep Space Tech Summit Key Visual

Full prompt

Futuristic cosmic tech poster featuring a low-saturation deep blue gradient background that deepens toward the edges. In the center, a luminous neon blue triangular frame emits a sharp self-illuminating halo, encircled by high-speed particle light trails and motion-blurred white and cyan streaks. The lighting radiates from the glowing triangular core, casting bright center contrasts against dark borders. Centered bold futuristic headline flanked by an upper sans-serif header 'HELLO WORLD' and lower thematic subheadings, harmonizing cyber technology with deep space exploration, 16:9 aspect ratio.
