A clean blank certificate template in vertical A4 format (3:4 ratio), based on the reference image. The outer frame features the delicate original dark green botanical foliage, thin dark-green outline border, and subtle green DNA double helix illustrations on light textured cream parchment. At the top center, the word 'ДИПЛОМ' is made visibly larger and more prominent across the top, styled with elegant classic serif lettering and decorative side flourishes. The entire central and lower part inside the frame remains completely blank, clean, and empty, with no other text, dates, names, or signatures.
