   bergbua.css next to this file is the bergbua corporate design, generated by
   ../sync-corporate-design.sh from the bergbua.at repository — never edit it
   here. Colour, type, the glass surfaces, the sky, the ridge and every
   component (.bb-*) come from there. This file is only what is this site's:
   the layout, the sticky header, the hero with its stats, the sections, the
   donation rows and the legal page.
