/* Public pages of newsletter.ritter-butzke.de (listmonk rbnews -> settings appearance.public.custom_css).
   Follows club.ritterbutzke.com: black page, white type, the white knight as the only mark, white
   buttons with black text, no colour. The site sets everything in Larsseit (Type Dynamic, commercial);
   DM Sans (SIL OFL 1.1, latin subset, wght 400-700) stands in until Ritter Butzke confirms their
   licence covers this domain - swap the file and the family name below to switch.
   Nothing is fetched from a third party: the font comes from this listmonk's own /uploads/ (the
   email template loads the same file; inlining it as well pushed the deploy command past 128 KiB). */
