In the provided image, keep everything absolutely identical and unchanged: the entire composition, background, lighting, central insulated copper refnet product, the main title 'Рефнеты K-Flex ST', the callouts 'Медный рефнет' and 'Толщина стенки', and all 4 cards on the right ('Защита от конденсата', 'Системы VRF / VRV', 'Энергоэффективность', 'Быстрый и чистый монтаж'). ONLY modify the single callout text pointing to the bottom insulation body: replace the phrase 'Плотное прилегание без мостиков холода' with a clean, clear Russian phrase 'Идеальная посадка без зазоров' in the exact same glowing cyan/white font style, size, and position with its pointer arrow intact. Do not change anything else.
