 * The section's forms — the graduate's questionnaire (page-alumni-join.php)

 * strips and buttons they use. Loaded with assets/js/pages/alumni/alumni-form.js
 * by enqueue.php wherever there is such a form.
 *
 * Same rules as the rest of the section: square corners, hairlines, semantic

 * field is wrong, a paragraph is centred, inputs are an underline with a 24px
 * font and no checkbox drawn, the submit button a white pill. None of it fits
 * here, so within this form it is taken back — by specificity, as in the
