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

Title: Neon Nexus Grid
Visual style: A pixel art cityscape rendered with a blend of sci-fi poster and vintage comic styling, arranged in a dynamic grid layout using bright candycore and classic comic primary colors with strong shadow casting to enhance depth.
Mood: hypnotic and energetic with a futuristic retro vibe
Core concept prompt: A high-energy pixel art cityscape composed in a balanced grid layout featuring futuristic buildings with neon edges and shadow cast effects that create depth and contrast. The color palette combines candycore pastel and bright comic primary hues. The style merges vintage comic book aesthetics with sci-fi poster elements, and minimal small cyber terminal style typography is integrated seamlessly but without prominent text. The composition feels hypnotic and dynamic with clean geometric lines and a bold silhouette.
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 brand logos, celebrity likenesses, political slogans, explicit content, 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.
