Minimalist American Baseball T-Shirt Design

1080x1080 square format, #D3D3D3 background, vector format, solid colors only, built-in negative space, make a minimalist American baseball scoreboard t-shirt design built around self-deprecating humor for people age 70 and up, use a centered layout with no decoration and plenty of empty space, feature bold black scoreboard letters “B” “S” and “O,” followed by three blue circles containing white letters “B” “A” “D,” two yellow circles containing white letters “B” “A,” and two red circles containing white letters “C” “K,” so the circles spell “BADBACK,” then place one bold statement underneath reading “BAD BACK, GOOD ATTITUDE,” use thick clean typography, flat vector shapes, strong contrast, and a simple screenprint style that stays readable from 10 feet away, with no extra icons, no shadows, and no cropped elements.
