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

Title: Neon Void Sentinel
Slogan: Guardians glow where logic fades
Visual style: retro-futuristic line art with glowing electric blue outlines on black
Mood: strange and unsettling
Core concept prompt: A bold silhouette of an abstract robotic sentinel figure, centered composition, rendered in clean retro-futuristic line art. The figure glows electric blue against a pitch black background, emphasizing sharp geometric shapes and glowing outlines. Text below in large, retro-futuristic block typography reads 'Guardians glow where logic fades' with a subtle halo glow effect.

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: real brand logos, celebrity likeness, political slogans, tiny unreadable text, human faces
- 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.
