E-commerce marketplace product card banner (Wildberries/Ozon style) for the physics workbook 'Физика в картинках 7 класс'. In the center/foreground, a clean, high-resolution, angled 3D mockup display of the attached book page titled 'ВОЗДУХОПЛАВАНИЕ' (page 18 with illustrations of the hot air balloon, bear with balloon, and Archimedes formula diagrams). At the top in bold, modern, stylish typography, the catchphrase/slogan in Russian: 'ПРОСТО И ПОНЯТНО'. The overall color palette and cozy aesthetic match the previous warm school physics classroom style (soft warm wooden tones, subtle blurred classroom background with scientific flasks, soft glowing studio lighting). Clean infographic layout, professional marketing graphic design for educational books, crisp legible details.
