Educational Russian language textbook cheat-sheet page in A4 vertical format, exact visual style and composition matching the reference image. Clean white page with soft modern educational workbook layout. At the very top, large bold red-coral title: 'ГРАММАТИЧЕСКАЯ ОСНОВА'. Below the title, brief clean Russian explanatory text with underlined syntax markings (single line under subject, double line under predicate). Below, two neatly structured rounded-corner tables with dark green thin borders and rounded headers: one table comparing 'Подлежащее' and 'Сказуемое', another table for types of predicates ('Простое', 'Составное глагольное', 'Составное именное') with example sentences in cursive Russian script with red accent highlights. At the bottom, a decorative dashed-border beige rounded card containing an exercise block 'Задание. Найди и подчеркни основу' with a cute hand-drawn ink bottle and feather quill illustration on the right. At the bottom center, small page number bubble with number '1'. Neat typography, high resolution graphic design layout, crisp vector workbook aesthetic.
