旅行海报，城市记忆

Create a premium beverage advertising poster for a fictional international soft-drink brand named FIERA GUAVA SPARK, designed as a single vertically composed three-panel campaign board where one bottled chilli-guava drink drives a clear emotional transformation from stress to refreshment to release. The final image must merge Orbit, Transit, and Port into one unified best solution: narratively immediate, materially persuasive, and graphically controlled. It should feel like a Cannes-level beverage campaign, a collectible lifestyle poster, and a globally premium retail ad board at once.

Build the poster as three horizontal cinematic panels stacked vertically with clean rounded-corner frame logic and thin dark separators between them. The same approximately 15-year-old Western girl appears across all three panels as the emotional anchor, while the drink bottle repeats as the constant hero object. The progression must feel instant and readable: pressure above, sip in the middle, liberated joy below. The bottle is the visual connector and emotional trigger in all panels.

Top panel: a moody desk-study scene showing the girl under schoolwork pressure. She sits at a cluttered table with scattered papers, notebook stacks, a warm desk lamp, a mug, and an open laptop. Her posture is tired and weighed down: one hand holding the forehead or gripping the hairline, the other near papers or keyboard. Expression feels drained, unfocused, and mentally overloaded, but still natural and age-appropriate. The drink is not yet the main action here, though the bottle can be subtly present nearby or introduced through color cues. Lighting is warm but oppressive, with a small pool of desk-lamp light surrounded by cooler dim shadows. This panel establishes the emotional problem.
