Морская трава

Use case: photorealistic-natural.
Asset type: one transparent botanical PNG sprite for an animated branch swaying around the base of its stem.
Subject: one graceful slender green seagrass stem with five gently curved blades. Premium natural botanical studio macro photography, soft diffuse lighting, realistic delicate texture, clean detailed cutout.
Composition: portrait canvas. The entire single stem or branch is visible, narrow silhouette about 35-45 percent as wide as it is tall. The bare bottom of its stem is placed at 54 percent of canvas width and 97.5 percent of canvas height, providing the animation pivot. Foliage extends upward with clear side and top padding; no leaf touches any edge. Not a bouquet or arrangement.
Constraints: Genuinely transparent alpha background, including holes and gaps within the object. Exactly one isolated reusable sprite. No floor, scenery, backdrop, checkerboard, external cast shadow, detached pieces, text, logos, border or watermark. Do not create an animation, finished background or montage.
