Commercial product marketplace photography card (infographic mockup) for an open physics educational booklet / magazine. An open, real printed book spread lies open on a warm brown wooden desk in cozy, warm studio lighting. The open spread exactly shows the two pages from the reference image: left page titled 'ПЛАВАНИЕ ТЕЛ' with floating body diagrams, right page titled 'ВОЗДУХОПЛАВАНИЕ' with the blue balloon, brown bear, hot air balloon, formulas (FA = p*g*V, Fпод = FA - Fтяж) and diagrams. At the top of the image, there is a large, bright yellow speech bubble badge with bold blue Russian text written in caps: 'ПРОСТО И ПОНЯТНО'. In the cozy blurred warm background: a wooden pencil holder with pencils, a glass science flask with blue liquid, chalkboard with faint formulas, soft bokeh. Professional marketplace banner, crisp detail, realistic mockup photography.
