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

Title: Half-Eaten Neon Avocado
Slogan: Bright Inside, Slightly Rotten Outside
Visual style: bold line art with neon glow
Mood: unsettling quirky
Core concept prompt: A large centered half-eaten avocado with a glowing neon yellow pit that looks suspiciously like a crudely smiling face, outlined in thick electric blue lines on a black background. The avocado flesh has exaggerated dripping textures with subtle slime effect, creating an awkward yet humorous vibe. The style is retro-futuristic line art, with bold silhouette and large readable text above and below saying 'Bright Inside, Slightly Rotten Outside' in chunky neon-yellow typography with electric blue shadows.

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, political slogans, explicit content, tiny 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.
