/* ==========================================================================
   Material Academy — Certification finder
   --------------------------------------------------------------------------
   Its own file because the component appears on two pages that load different
   stylesheet sets: index.php via theme-head.php, certifications.php via
   head.php. One definition, loaded by both.
   Requires tokens.css.

   18. Certification finder
   --------------------------------------------------------------------------
   Sits between the trust strip and the certifications. Was a bare input that
   submitted to registration.php - searching for a course landed you on the
   signup form - and it lived inside the hero with its heading orphaned in a
   separate block above the form.
