Objective: For{argument name="observance date" default="May 14th"} Create a vertically composed Japanese promotional poster for "Thermometer Day," combining simple educational infographics with a realistic model wearing a themed T-shirt. Canvas: High-ratio social media poster, 9:16 aspect ratio, light icy blue background, soft clinical medical-style lighting, simple magazine-style layout, blue and red color scheme. Subject: On the right half, a realistic young Japanese woman with a neat chin-length black bob is placed, facing the camera from above the thigh. Her face is deliberately obscured by a simple rectangular blur/mosaic block. She wears a fitted short-sleeved gradient T-shirt, the color grading from sky blue on the left to pink/red on the right. The text on the T-shirt must be clearly displayed: the first line "5/14", the large text below "Thermometer Day", and the smaller text at the bottom "Birthday of a Doctor Physicist Farmer High". She lightly holds a white electronic thermometer near her shoulder with her right hand. Top Area: Place the prominent Japanese title "May 14th is" and "Thermometer Day" on the left, with "Thermometer" in dark blue and "Day" in red. Add a small, line-style thermometer icon above/to the right of the title, labeled "°C". Below, add the subtitle: "— Supporting the evening, the temperature day—". Add a short Japanese description explaining that May 14th is Thermometer Day, related to the birthday of German physicist Fahrenheit, and emphasizing the importance of temperature measurement for science, daily life, safety, and comfort. Decorative Icons: Add three light blue science/weather icons to the upper left background: one vertical thermometer icon, one globe icon, and one laboratory flask icon. Central Infographic Area: Add the title "Scenes of active thermometers," underlined in yellow. Below this are three horizontally arranged rounded rectangular cards, each with a blue border, a small icon, a bold Japanese title, explanatory text, and a photo thumbnail: 1. Heart icon, titled "Health Management," with text about measuring body temperature and early detection of bodily changes; the thumbnail shows an electronic thermometer displaying 36.5 degrees Celsius placed on a soft towel. 2. Cooking pot icon, titled "Cooking and Bathing," with text about cooking temperature control and bath water temperature adjustment; the thumbnail shows a thermometer inserted into a steaming cooking pot. 3. Laboratory flask icon, titled "Research and Industry," with text about how precise temperature measurement supports technology and product development; the thumbnail shows a glass beaker/test tube with a pipette. Bottom Area: Add a dark blue closing title, "How do we know temperature? How do we protect the future?", below which is a thin horizontal line, two lines of smaller Japanese explanatory text about climate awareness and protecting life and the future of the planet, ending with a red call to action: "Why don't you pay attention to the temperature today?" A light green-blue "Earth and Sprouts" icon is placed in the lower right corner. Visual Style: A simple Japanese public information poster, with realistic photographic style for the model and card thumbnails, flat and minimalist icons, soft shadows, rounded corner cards, ample white space, professional print layout, no watermark, and no additional logo. Uses clear and legible Japanese fonts and strictly adheres to the following layout: a top title area, a model image, three decorative icons, three application scenario cards, and a bottom information area.
