Spooky Coffee Mom Line-Art Tee

Create a centered t-shirt design featuring a line-art style with a playful, hand-drawn aesthetic. Include spooky doodles like haunted mugs, bats, pumpkin cups, and cobwebs for a coffee mom. Centered phrase: "Behind Every Spooky Day Is a Pumpkin Cup". All elements must be clean white line-art only with no fill, optimized for printing on dark shirts, with a fully transparent background.
