/* GVERA website. Same language as the app's Simple view: cool neutral paper (or night), blue-black ink and one
   signal colour, the deep cyan of the mark. One theme per page, light or dark, following the system unless the
   visitor picks (the sun/moon button). Shape rule, followed everywhere: panels 16px, controls and pictures 10px,
   pills fully round. Type is Geist and Geist Mono (SIL OFL), icons Phosphor (MIT), tool marks Simple Icons (CC0);
   all of it is served from this site, nothing loads from a third party. */
