Allow for theme color differences between web app and standalone app

I've always been a light theme user (since before dark theme was a thing), and always felt it worked really well for me. Since I moderate the Discord server for a rather small game, I pretty much always have Discord open at work too.

However, I use the web app at work, and then come home and use the standalone app.

With the new change to light theme, I have to keep switching my theme depending if I'm at work (in which most of my work is a lighter theme, so it blends better with my workspace) and when I'm at home (where I have a mixture of light and dark theme apps).

The mobile app already can be desynced from the desktop apps, and I always had that on dark theme. Having some way to change my theme based on which desktop app is being used (or perhaps having an option to use the original light theme) would be stellar!
