/* =========================================
   ANGUTSA CHAMPIONSHIP — AUTHENTICATION SHELL
   Shared layout for the authentication and account screens:
     login.html, forgot-password.html, reset-password.html and
     registration.html (which also loads css/registration.css)

   Keeping the shell in one file avoids duplicating the same layout
   rules across four pages. Form primitives (fields, checks, buttons)
   live in css/base.css.
