/* ==========================================================================
   Admission application modal

   Opened by any link carrying data-admission-popup (see js/admission-modal.js).
   A custom front end for the existing Zoho CourseApplication form: it shows
   only the fields Zoho marks as required. Submission is not wired up yet.

   Everything is scoped under .admission-modal. The site carries legacy CSS
   (global p/label/input rules, `h2 span`, bare `a` background) and
   Bootstrap 3, so colour, alignment, spacing and form-control styling are
   pinned here rather than inherited.

   Look: the navy of the page's admissions band (.dsa-adm), a translucent
   glass card with the band's thin white edge, the 3px orange eyebrow rule,
   and the amber solid button (.dsa-btn--solid). The form sits on an opaque
   white sheet inside the glass so the inputs keep full contrast.

   The Get Callback popup (Popup-contact-window.php) sits at z-index 99999;
   this modal stacks above it and shares none of its classes or IDs.
