 * Title:  APL Form Builder - public form styles (Online Application look)
 * Author: Alex Nguyen
 *
 * Reproduces the Library Card Online Application's design tokens, header,
 * card and footer (register/online-app/assets/css/styles.css) and restyles
 * Bootstrap 5's form controls to match: Source Sans 3, COA blue-dark
 * headings, green compliant primary buttons, 1.5px gray borders with an
 * 8px radius. Loaded after bootstrap.min.css so these rules win. Also
 * loaded on the intranet form page for the form-specific pieces; the
 * chrome rules there are inert because page_header.php owns the header.
