A clean blank certificate template based on the provided image, in 3:4 aspect ratio. Keep the exact same green botanical watercolor border, leaf foliage, DNA double helix illustrations, light textured parchment background, and only the centered header word 'ДИПЛОМ' with its decorative flourishes/swirls at the top. Completely remove and erase all other text: delete the recipient name, description paragraphs, teacher name/signature line ('Преподаватель Биологии...'), and date ('23.08. 2026'). The central and lower area inside the decorative frame must be completely empty, clean, and blank, ready for custom text placement.
