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

Title: Galactic Dunk Salmon
Slogan: Swim through Portals, Shoot for Quasars
Visual style: bold black line art with glowing swirling portals and misty emission creating a centered silhouette of an astronaut salmon playing cosmic basketball
Mood: quirky and slightly unsettling mix, evoking cosmic whimsy with a hint of surreal mystery
Core concept prompt: A bold, glowing black line art illustration of an astronaut salmon dribbling a cosmic basketball, surrounded by swirling glowing portal shapes with misty emission effects in a centered composition on black background. Text below in large, clear typography reads 'Swim through Portals, Shoot for Quasars'. The design is quirky with a slightly unsettling cosmic atmosphere, no additional background or scene.

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 symbols, explicit content, tiny unreadable text, background scenes
- 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.
