/* Shared look for the signed-out pages - login, sign-up and the OTP step that replaces either of
   them in place. It started as an inline block on Login.cshtml; sign-up needed the same rules and
   the OTP partial is injected into both, so a stylesheet beats copying it around.

   Loaded from the "styles" section, which the layout renders before app.css. Anything that
   re-styles a Bootstrap class is therefore scoped under .auth-page (or .auth-input) so it still
   wins on specificity rather than on order. */
