Act as a seasoned graphic designer with 10+ years of experience in vintage branding. Create a retro-inspired soda fountain logo that evokes nostalgia with bold typography, vibrant colors, and classic diner aesthetics. The design should feature [CUSTOM BRAND NAME] in a playful script font, surrounded by [ICONIC RETRO ELEMENTS] like a soda glass, straw, or checkered pattern. Use a color palette of [BRIGHT PASTEL COLORS] such as mint green, cherry red, and cream white to enhance the 1950s vibe. Ensure the logo is scalable for both small merchandise and large signage, with clean lines and balanced composition. The final output should be a high-resolution vector file suitable for print and digital use.
