   The layout is the original one — title with a facts cluster, two-up prose
   sections, figure plates, two-up figure rows, "other projects" cards. Only the

   hairlines from site.css, square corners instead of the 16px radius.

   Loaded after styles.css and site.css, so it overrides the original px/Geist
   values. Rules are scoped with .site where the shared reset in site.css would
