/* ==========================================================
   PUBLIC / SIGNUP LANDING PAGES
   ----------------------------------------------------------
   Owns the public landing/login page and the register/* signup
   step pages (entry-card panels, the interest/topic pill picker,
   and the usage-intent choice cards). Do not duplicate the
   entry-card/form-stack/field-* primitives here — those live in
   the shared admin-and-public CSS files; this file only owns
   layout/composition specific to these pages.
