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

Title: Mechnoir Crest
Visual style: pop art meets deconstructed oil painting collage in deep ocean tones
Mood: underground, eerie, and immersive
Core concept prompt: An oil paint style collage in deep ocean blues featuring a bio-mechanical human heart merged with a vintage motorcycle engine, overlaid with a glitch-distorted human face fragment. The composition forms a crest layout positioned at the corner of a black shirt. Double exposure and paint drip effects highlight the maximalist deconstructed elements, accented by minimalistic handstamp typography styled with psychedelic lettering and runic symbols, all balanced for a low energy, medium complexity underground vibe.
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 messaging, 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.
