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

Title: PORTAL PANIC
Slogan: WHEN WORLDS COLLIDE, STAY CALM
Visual style: Minimalist electric blue line art on black background with glowing portal shapes and whimsical exaggerated character expressions.
Mood: strange
Core concept prompt: A centered whimsical line art figure with exaggerated panicked expression bursting through glowing electric blue portal-like shapes on a solid black minimalist background. Motion lines emphasize frantic movement. Above and below the figure, large all caps text reading 'PORTAL PANIC' and 'WHEN WORLDS COLLIDE, STAY CALM' in electric blue glow, ensuring high readability.

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 likeness, political slogans, explicit or sexual 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.
