Create a square t-shirt graphic design with the following concept:

Title: Neon Ninja Paradox
Slogan: Silent but Glowing
Visual style: Retro-futuristic line art with neon glow
Mood: quirky and strange
Core concept prompt: A centered silhouette of a ninja striking a dynamic pose, rendered in clean neon yellow and electric blue line art with a subtle glow effect on black background. The ninja wears a futuristic visor and has abstract glowing circuitry patterns on the suit, combining retro-futuristic style with a bold silhouette. Large, crisp typography below reads 'Silent but Glowing' in a neon yellow streamlined font.

Hard constraints:
- Keep composition centered and shirt-print friendly.
- Use high-contrast, clear forms suitable for print.
- Any text must be large and easily readable.
- Exclude all forbidden elements: eyeball, banana, cosmic patterns, octopus, half-eaten avocado, origami crane, real brands, celebrity likenesses, small unreadable text
- Do not include real brand names/logos, celebrity likenesses, copyrighted characters, political campaign slogans, hateful content, or explicit content.

Output a clean standalone design graphic, no mockup, no watermark, no background scene.
