Subject: Add dark-mode option
X-Git-Url: https://git.owens.tech///git?a=commitdiff_plain;h=8ce1f06da17689f11ba0ff389b96c5b363820e23;p=vimb.git

Add dark-mode option

This lets websites use the `prefers-color-scheme` media query to adapt
styles according to user preference.

It also affects internal pages like about:blank.
