Design a vintage circular badge logo for a brand. In the center: a simple line-art illustration of {{central_icon}} in a single {{ink_color}} ink weight. Curving along the top arc of the badge, the brand name "{{brand_name}}" in a bold condensed serif, letterspaced wide; curving along the bottom arc, the words "{{tagline_or_year}}" in a smaller matching serif. Two thin concentric circular rules frame the text, with a small decorative star or diamond separating top and bottom text on each side. Flat two-color design: {{ink_color}} artwork on a {{background_color}} background, slight vintage print texture, perfectly centered, no other text or elements — in the tradition of national park badges and craft roastery stamps. Text-in-logo technique: - Nano Banana Pro is currently the strongest model for curved, correctly-spelled logo text — but only when the exact string is in double quotes and each string gets its own type instruction. One quoted string per text element, never "add the brand name somewhere". - Keep {{brand_name}} under ~14 characters for the top arc; longer names crowd the curve and letterforms start merging. Long name? Put it straight across the center and move the icon up. - {{central_icon}} must be line-art simple: a pine tree, an anchor, a coffee cone. Detailed icons fight the text for the badge's tiny real estate. - Verify spelling character-by-character before using — errors cluster at arc ends (the first and last letters). - Rerun with only the quoted strings changed to build a family of badges (locations, product lines) with the same structure.
