/* Cairnova — cairnova.io
   One stylesheet. No framework, no build step, no JavaScript, no tracking.
   Fonts are self-hosted (Manrope, SIL OFL) so the page makes no third-party requests.

   Theming: every colour is a token on :root. The dark theme redefines the tokens under
   prefers-color-scheme; nothing else changes. Forced-colours (Windows high contrast) gets
   explicit borders where colour alone would otherwise carry meaning. */
