Visual changes, copy tweaks

Description of the Change

These include mostly visual changes to tighten up the interface and make it more accessible. Slight tweaks to the copy are also included.

Alternate Designs

Since all of my changes are straight-forward and explained in the different commit messages, I'll use this to spitball some other designs I had in mind but wasn't able to implement for one reason or another:

The title bar may not be needed. The web app handles the standard browser back button fine and the reload button is deadweight. The PWA on Windows also has a refresh and back button, so they aren't needed there.
The version string can be added to the page title or just above the settings drawer's footer
I can't figure out where the popover code is but the animations are a bit much, might want to speed those up and reduce the distance it has to travel when sliding in. It should at least respect the prefers-reduced-motion setting.
Loading favicons fail more often than not when using the strict https://xyz.com**/favicon.ico** pattern, might want to use something like Google's S2 favicon API or FaviconKit.

Benefits

Animations are tighter, colors more closely adhere to WCAG AA standards.

Applicable Issues

I removed a rogue

from the featured content card, I don't think this was used for anything but if it is or breaks something, feel free to reject that change.
