fix: remove header a ::before

you will have to modify your html files to divide the header nav links after this, like v1 and new.css@v1

removed because it causes a visual issue when hovering over the link and it seems like it's better to have your own divider

dev.css

···
 	margin: -2rem calc(50% - 50vw) 2rem;
 }
 
-header nav a + a::before {
-	content: "• ";
-	color: var(--dc-tx-2);
-}
-
 header * {
 	padding-top: 0rem;
 	padding-bottom: 0rem;
