A commercial-grade, award-winning design for a 3:4 vertical flyer. The theme is 'Streetwear' meets 'High-Tech'. The focal point is a floating, glassmorphic code editor window displaying vibrant, neon-lit syntax highlighting. The background features a gritty yet clean urban studio aesthetic with matte black textures and subtle concrete grain. The headline 'Code Snippet Beautifier' is executed in bold, oversized typography with a slight chrome distortion effect. The sub-headline 'Code-to-Image Generator' is placed with perfect breathing room using a minimalist technical font. Visual elements include floating 3D tech-wear buckles and subtle fabric textures integrated into the UI layers. Professional studio lighting with cold blue rim lights and sharp shadows creates a masterpiece of depth. Agency-grade post-production ensures 4k resolution, crisp lines, and a high-end commercial finish. The composition adheres strictly to the 3:4 aspect ratio, ensuring a balanced visual hierarchy and a sophisticated professional palette.
