Design Improvements

[kentcdodds]

• /account
• /discord (also a way to get there)
• /admin (also a way to get there)
• /chat - new page that's basically the full screen version of the chat view here: https://foundations.epicweb.dev/01/01/problem?preview=chat
• Presence faces on the bottom left (maybe we keep them there? Maybe we move them?)
• Progress - Everywhere I'm displaying progress looks bad. I like the way it looks on epicweb.dev. We should just do it that way.
• Theater Mode - In general we need better space management. Especially for mobile view (useful for the deployed version of the app). And the instructions aren't wide enough for the videos to be useful without going full-screen which can be a problem if you have an ultra-wide monitor. So having a nice way to make the video bigger without being full-screen would be good.
