A minimalist final slide for a social media carousel, matching the style and colors of the provided cover image. The background is a solid, plain, dark blue-grey color (taken directly from the dark screen in the background of the classroom). There are absolutely no icons, no physics symbols, and no drawings. In the exact center, there is clean and modern typography: the main word 'Подписывайся' is written in a large, bold, premium golden sans-serif font. Directly below it, the subtitle 'тут про речь и публичные выступления' is written in a clean, crisp, medium-sized white sans-serif font. The layout is perfectly centered, spacious, and professional.
