Senior Baseball Code T-Shirt Design

3. **1080x1080 square format t-shirt design with a #D3D3D3 background, vector format, solid colors only, built-in negative space, and the entire graphic fully contained inside the frame with no cropping; create a minimalist senior baseball humor design using the proven bestseller structure of one dominant headline and three short definition lines, with “SENIOR BASEBALL CODE” across the top in bold collegiate block type, a centered baseball home plate silhouette behind the title as a flat solid shape, then three readable code lines beneath: “ERA = EARLY RETIREMENT”, “RBI = REST BEFORE INNINGS”, and “BP = BACK PAIN”; use solid black text with warm ivory highlights and a muted maroon accent line, keep the composition centered and balanced, use thick strokes, wide tracking, strong negative space, no gradients, no tiny text, and make the design feel like a vintage team practice shirt.**
