Build me a modern meeting web app called Meeting Hub.

I want a clean dark mode interface where people can start or join video calls in the browser, with real time audio and video, screen sharing, and an in call chat that saves messages. It should let guests join without making an account, but also have protected member areas for hosts and admins. Include a simple schedule page for setting up meetings and generating invite links, plus a recordings area where people can play back and download past meetings.

Use the existing PHP setup and make it feel polished, responsive, and easy to use on desktop and mobile. Keep the design sleek with soft glassy cards and subtle glowing effects. Make sure the app handles meeting signaling, chat updates, and basic device settings like camera and microphone selection. If you need current WebRTC or browser API details, look them up online first.
