/* ==========================================
   Site-wide UI kit
   Loaded on every page (lib/main.server.dart). Carries the visual language
   of the redesigned homepage (home.css) to the header, footer, dialogs and
   every other page. Page-specific layouts live in their own files
   (programs.css, course.css, contacts.css, blog.css, trial.css).
   Motion is enhanced by web/scripts/site.js; without it every section is
   fully visible and usable.
