New Themes and Stylesheets

This is only a rough start, because a lot of the site’s interface (and therefore colors) weren’t visible in screenshots I could find. So, if you set your theme to dark gray or dark orange, and then use this in a userstyle, you get close-ish:
Updated with exact values from byte[]:
i.favicon-home {
	mask-image: none !important;
	-webkit-mask-image: none !important;
	background-color: transparent !important;
	top: 0;
	
	background-image: url("/preenhub.svg") !important;
	background-position: 50%;
	font-size: 20px;
	vertical-align: middle;
}

@media (min-width: 1150px) {
	.header__link .fa__text { display: none; }
	
	i.favicon-home {
		background-image: none !important;
		font-family: inherit !important;
		
		display: flex;
		align-items: center;
		flex-direction: row;
		font-weight: bold;
		font-size: calc(var(--header-height) - 8px);
	}

	i.favicon-home::before {
		content: "Preen";
	}
	i.favicon-home::after {
		content: "hub";
		display: flex;
		flex-direction: column;
		justify-content: center;
		background: var(--base-color);
		border: 1px solid var(--base-color);
		border-radius: 4px;
		color: var(--background-color);
		height: calc(var(--header-height) - 8px);
		margin-top: 4px;
	}

Nice, I’m choosing dark green and that’s gonna be my default color from now on. Also, the logo change looks cool.

My two cents: The logo hardly looks different at all, and that’s good! It’s simple, to the point, and uncomplicated.
Also, cool to have a more sort of “DIY” mix-and-match approach to the themes. I’m personally fine with the light theme (so shoot me, dark theme nerds :P), but I can see this as being fun for users in general!

Garp.
< the site logo changed
.. I’m one of those people who probably wouldn’t have noticed this if it hadn’t been mentioned :D
And ha, as long as you don’t do updates like VK, Tumblr or Twitter, everything is fine.

Choosing a design to your taste is cool!!! Thank you
