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

Title: Pixel Samurai Grid
Visual style: A vibrant pixel art depiction of a samurai warrior layered with double exposure gradients, arranged within a structured grid layout combining acid pop and candycore color palettes.
Mood: Underground high-energy with a futuristic rebellious edge.
Core concept prompt: Pixel art of a samurai warrior featuring gradient mesh and double exposure effects, using a sandstone, acid pop, comic primary, and candycore palette. The design is composed in a clean grid layout with minimal cyber terminal style typography elements, creating a high energy, medium complexity underground vibe.
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, celebrity likeness, copyrighted characters, political slogans, explicit content
- 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.
