/* =============================================================
   BTH Owned Form — Tier-1 commit skeleton
   Source: BTH/design-system/templates/bth-forms-cta-spec.md
   Pair with bth-system.css (tokens) + bth-form.js (behavior).

   One skeleton for every BTH form (signup / contact / waitlist):
   eyebrow -> headline -> copy -> field(s) -> Tier-1 button -> fine print.
   This file is the shared, page-independent version of the legacy
   per-page .form-card / .ml-form-wrap / .form-input rules — every
   page that includes this file gets the identical production form,
   regardless of what local styles it also carries.
