Modify the uploaded image by keeping everything exactly the same (the 3D cartoon boy sitting at the school desk studying, the physics workbook mockup 'ФИЗИКА В КАРТИНКАХ', all text headlines, icons, formulas, and color badges), EXCEPT in the bottom green badge on the lower left: remove the words ', тонкая обложка' so the badge text simply reads 'Удобный формат (А4)' or 'Удобный формат А4'. Ensure all other text, Russian typography, characters, colors, composition, and visual elements remain identical to the original image.
