/* Design tokens shared by every program in the suite (Option D "Chambers").
   A program may override any of these in its own stylesheet, loaded after this one.

   FONTS: no web fonts are loaded today, so the stacks below fall back to fonts already on the device.
   To self-host a font (e.g. Source Serif 4), put the .woff2 file in static/fonts/ and add ONE block here:

   @font-face {
     font-family: "Source Serif 4";
     src: <the font file path, written as a CSS URL starting ../fonts/> format("woff2");
     font-weight: 200 900; font-style: normal; font-display: swap;
   }

   then put "Source Serif 4" first in --font-serif. Nothing else needs to change. */
