/* ==========================================================================
   vivce#1086 — Registration wall (guest-only). Enqueued by lib/registration-wall.php
   only while the wall is on and the visitor is a guest.

   Visual language = the launch homepage (css/home-launch.css, #1085):
     teal      #0D7377  white text 5.62:1 (AA)   — primary button, links, lock
     teal deep #0A5C5F  white text 7.75:1 (AAA)  — hover
     wash      #E6F4F4  teal text 4.98:1 (AA)    — chips, lock badge, note
     ink       #18191C  / slate #5E626E
   Montserrat for headings (the theme already loads it), Inter for body.
   The teal underline swoosh reuses img/blue-shape.png (critical-child.css).
   The explainer modal reuses template-parts/global/modal.php + .modal-form.
