Create a vintage-inspired 9:16 scrapbook poster for blueberry lavender soda with a dreamy artisanal cafe advertisement aesthetic. Feature a sparkling layered blueberry soda with lavender cream foam and translucent ice cubes, blending ultra-realistic beverage photography with playful hand-drawn doodles and pastel marker sketches. Show fizzy carbonation bubbles visible through the glass, soft purple-to-blue gradient drink tones, a creamy white foam top, glossy condensation droplets, and realistic glass reflections. Surround the drink with whimsical handwritten cafe notes, tiny ingredient arrows, delicate lavender flower doodles, bows, stars, tiny moons, blueberries, and sparkles. Use a sticker-book collage layout with torn paper textures, washi tape accents, textured notebook scraps layered organically across the composition, and cozy Korean dessert cafe moodboard styling. Add cute props such as vintage spoons, blueberry pastries, mini flowers, recipe cards, cassette tapes, and polaroid snapshots. Use warm cinematic natural window lighting, editorial flatlay cafe photography mixed with journal-style illustrations, a nostalgic Gen Z cafe aesthetic with Y2K undertones, a dreamy soft-focus atmosphere, highly detailed scrapbook composition, social-media-ready dessert shop poster energy, and a soft pastel lavender, dusty blue, cream, and silver color palette. Make it feel like stylish lifestyle cafe photography and a premium editorial food advertisement. Output aspect ratio: 9:16.
