Absolutely not staff, but I scotch taped together some (very rudimentary) dark-ish mode that can be applied as a user script that can be used with your userscript application of choice:
// ==UserScript==
// @match https://dynasty-scans.com/*
// ==/UserScript==
(function() {
const s = document.createElement('style');
s.type = 'text/css';
s.innerHTML =
"a { color: Silver;}"+
".pages-list a {color: Whitesmoke !important;}"+
"body {background: #003366 !important; color: Whitesmoke !important;}"+
"#content {background: #3b6b9c !important;}"+
".chapter {color: Whitesmoke !important;}"+
".user {color: Black;}";
document.getElementsByTagName('head')[0].appendChild(s);
})();
(Usually I wouldn't recommend people to run scripts found somewhere on the internet, but this obviously only does some pretty poor CSS work.) You can also probably turn this into a bookmarklet with minor modifications.
I'm not all to sure whether a dark mode makes sense when the supermajority of stuff here assumes dark on a bright background, but at least in the case of black and white it should be trivial to just invert the loaded images.
I'll probably look into turning this into something less ... haphazard (this was literally made in 5 minutes, okay?). I.e. properly hosting it somewhere, ironing out the theme, etc., unless there is a signal from staff dark mode support it on their end.
