/* Invoir design system. One stylesheet for invoir.dev (static, built by site-src/build.py) and
   validate.invoir.dev (the app: validator, login, dashboard, admin). The build copies this file to
   site/assets/site.css and app/src/main/resources/static/assets/site.css: edit it here only.

   Rules that keep pages from jumping when you move between them:
   - one header (64 px, same links on every page), one footer, one container width;
   - the scrollbar's space is always reserved (scrollbar-gutter), so short and long pages line up;
   - the font is self-hosted with font-display: optional, so text never re-flows when it arrives;
   - light theme only. */
