Generate a Roblox classic shirt template of a hyper-realistic black designer puffer jacket. Include accurate padded textures, glossy nylon sheen, metallic zippers, stitching detail, and natural folds. Make the design look expensive and premium, similar to luxury fashion brands. For the back, add the text ‘STXMINAA’ in a clean Gothic-style font (not cursive). The lettering should look like high-end streetwear branding, bold and centered. Use the classic Roblox 2D layout: torso front/back/sides
