/* =========================================================================
   Register page (modernized)

   Shares the visual chrome of the login page (slate gradient backdrop,
   white card, 1League logo + SPORTS HUB tagline, primary blue accent)
   so the two auth screens feel like siblings. Self-contained: depends
   only on its own --register-* tokens and the Roboto font.

   Layout:
     - body.register : full-viewport gradient
     - .register-shell : centered flex container
     - .register-card  : white rounded card holding everything
     - .register-grid  : 2-column responsive form grid
                         (first/last + password pair occupy 1 col each;
                          username, email, confirm-email span both)
     - .register-error : surfaces server-side registration_failed banner
