/* ─────────────────────────────────────────────────────────────────
   BCF Overlays — Field-card + Input-overlay pattern.

   The signature mobile-input UX: tappable field cards open a
   fullscreen sheet (mobile) or centered modal (desktop) with a
   single big-text input. Solves the tiny-mobile-input problem once
   for the whole site.

   Used by: register, login, forgot/reset, intake, app forms.
