/* Departments and Academic Departments lists — scoped styles (prefix: .dl-)
   Shared by department_list.html and academic_department_list.html through
   university/includes/department_grid.html. The brand blue comes from the site
   theme (--bs-primary in styles.css); the Roboto Slab font is inherited from the
   body. styles.css loads after this file, so every rule here is scoped under
   .dl-page to win over its element rules (`a` colour). */
