/* ============================================================
   AccruFlow — Premium Onboarding Flow
   Phase G.5h (2026-05-27)

   Scope: 5-step register/onboarding modal launched from index.html
   when the user clicks "Register here". Replaces the legacy single-
   step signup form with a Stripe/Linear/Ramp-style flow.

   All rules are scoped under .acf-onb-root to avoid clashing with
   main.css / academy.css. Inter typography (already loaded). Mint
   accent (#00d4a8) to bridge Academy → App brand transition.
