zygoexpresssupport-sketch/zygo-express-hub ? reverse-engineered prompt

Build me a clean, modern web app for Zygo Express Hub that feels like a support and help center for customers.

I want it to look polished and easy to use on desktop and mobile, with a simple homepage, clear navigation, and a place for people to find help fast. Include sections for common support topics, contact or request help, and a simple dashboard style area if that makes sense for managing support info. Keep the design friendly and professional, with smooth spacing, good typography, and a layout that feels finished.

If you need to look up current docs or best practices online, go ahead. Please make the whole thing work well as a real app, with sensible placeholder content where needed, and keep it easy to extend later.
