Instagram-Post für eine Hashtag-Kampagne rund um UGC

Create a vertical 9:16 Instagram-style social media post for a brand UGC campaign. Show a clean mobile-first layout with a bold branded hashtag as the hero element, a collage/grid of diverse customer-generated photos and short video stills, and subtle UI-inspired elements suggesting a feed of submissions. Include concise callouts for reposting to stories, saving to highlights, featuring in a shop listing, and showcasing social proof on a website. Style should feel contemporary, energetic, and highly shareable, with strong contrast, crisp typography, and a polished but social-native look. Use realistic content placeholders, layered cards, and a clear hierarchy that makes the hashtag feel central and memorable. Avoid clutter, tiny unreadable text, generic stock-photo vibes, overly corporate design, and any visible platform logos or trademarks. No landscape composition; keep everything optimized for vertical 9:16.
