/* Nyrox showcase site. No framework, no build step: one stylesheet.
   Light by default, dark only when the toggle in the header says so
   (theme.js sets data-theme on <html>).

   Type is IBM Plex, served from this site (assets/fonts, SIL OFL 1.1) so no
   visitor request goes to a third party. Layout favours rules, lists and
   tables over boxed cards: the content is reference material and reads as
   such. */
