/* PanPhy design system: Spectrum.
   One file of fonts, color tokens and a few shared components for every app.
   Apps keep their own layout CSS and map their variables to these tokens.
   Load after /assets/fonts/fonts.css (for IBM Plex Mono) and before app CSS.
   Font URLs are relative to this file and resolve to /assets/fonts/.
   Every change here changes the shared files, so every offline app prompts to update. */
