Google Sites Page

I need help building one hidden Google Sites page for an academic conference presentation. The site is already created, the custom domain is connected, and the page already exists. This is not a full website build. The task is to create a clean, mobile-friendly resource page using text, PDFs, images, media links, and section instructions that I will provide. The page supports an academic poster presentation. The style should be professional, simple, readable, and appropriate for a university professor, musician, and researcher. Tasks include: Build one Google Sites page using provided content Add clear headings and section spacing Upload or embed a poster PDF Add buttons or links for recordings, videos, publications, and resources Use descriptive link labels Check mobile readability Send preview/screenshots for review before final publishing
