Create a centered t-shirt design in a retro groovy style using clean white line-art on a transparent background. Use wavy, flowing 70s-inspired typography for the phrase: “Peace, Love & Screams” curved in a playful arch. Surround the text with whimsical doodles such as haunted bows, bats, cobweb sparkles, and spooky hearts. All elements must be clean white line-art only with no fill, optimized for printing on dark shirts, with a fully transparent background.
