Title: Neon Pulse Turtle
Slogan: Slow Glow, Fast Flow
Visual style: retro-futuristic line art with neon glow
Mood: quirky and strange
Core concept prompt: A centered bold silhouette of a turtle in retro-futuristic line art style, glowing in neon yellow and electric blue on black background, with pulsating light effects emphasizing the shell's geometric pattern, large legible text below saying 'Slow Glow, Fast Flow' in futuristic typography

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.
