/* Fresco: the teacher portal's look since October 2026. Calm white surfaces, one indigo
   for actions, cyan for what is new, green for what works, and Sora + DM Sans.

   It covers the portal's own chrome (menu, mobile bar, sign-in, News), every page that is
   not on a class route, and the Materials pages for browsing (.fresco-page: the index, a
   level, a block). Class routes (src/data/classroomThemes.js: /materials and /tools) carry
   [data-classroom-theme-root] on <main>, which the selectors below leave out, so the class
   itself (.module-workspace-page) and the other classroom views keep their classroom look.

   Loaded last in index.html. Earlier sheets (the kid theme in styles.css and
   no-gradients.css) set colours with !important, so the overrides here need it too. */
