/* Auth overlay — sign-in / forgot-password / set-password.
   Card-overlay pattern adapted from Reverie's login-screen, in
   Fold's class-driven style (no inline styles). The three forms
   live inside one card; .auth-overlay[data-state="..."] toggles
   which one is visible.

   Bug noticed in this file? Cross-check Reverie + Practice — they
   share the Supabase flow, each has its own UI implementation. */
