Coastal City Travel Life Collage

Generate a single collage image in a nine-grid travel lifestyle photo style: one day of the same young woman in a seaside town, including natural moments such as street-side coffee, sea breeze selfies, back view at dusk, and holding an iced drink. The overall look should be like a real mobile phone life record but with a high-end and unified aesthetic, suitable for demonstrating life photo generation effects. Do not show social platform interfaces, text, avatars, logos, watermarks, or dates.
