Über dieses Design

an illustrated coffee mug sits centered, the bold retro words "DAD FUEL" printed across the mug; rising steam curls into a heart shape above the mug; the name "James" is written on the side of the mug. TEXT RULES (critical): spell every word correctly and in full; render each text string EXACTLY ONCE — never duplicate, echo or repeat any word; do not let any icon or graphic replace or hide a letter. The only text is: "DAD FUEL" (across the mug) and "James" (on the mug side). Style: bold retro diner aesthetic, warm cream, red and brown palette, thick outlines, bold clean vector, high-contrast and print-ready
