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

Title: Shards of the Mecha Underground
Visual style: Minimalist mecha design with bold comic primary and acid pop colors, featuring gradient mesh and 3D depth effects combined with shattered glass overlays.
Mood: Sarcastic underground vibe with medium energy, evoking rebellious and edgy aesthetics.
Core concept prompt: An asymmetrical composition featuring a minimalist mecha silhouette rendered in bold comic primary and acid pop colors with gradient mesh shading and 3D depth effects. The mecha image is overlaid with fragmented shattered glass patterns repeated as icons across the design. The typography is minimal, using stencil style fonts in small quantities, placed to balance the irregular layout. The overall style is clean yet edgy, blending sharp geometric shapes with smooth gradient transitions.
Typography density rule: Use at most one tiny, simple brand-like mark or short label only if essential; the graphic must remain primarily visual.

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 brands, celebrities, explicit content, political slogans, tiny 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.
