A friendly flat vector illustration of two hands meeting in a confident handshake, centered within a clean partnership announcement composition. Use the Brand Colors throughout the illustration, with clear color blocking, smooth rounded shapes and subtle tonal variation for depth. Place the Announcement Text prominently above the handshake in bold, highly legible sans-serif lettering, with generous spacing and strong contrast. Add a few restrained geometric accents around the subject to suggest collaboration and momentum without cluttering the layout. Keep the background simple and balanced, with a polished social media graphic finish. Use the Format, maintain crisp edges and render the wording exactly as written without misspellings or extra text.
