/* =============================================================================
   Auth pages (login, change / forgot / reset password, access denied).

   Colour is driven by the --brand-* CSS variables emitted per-request from
   BrandingOptions, so re-theming stays a config change.

   Every auth page sits over a cane-field backdrop (the login poster + a green
   scrim) for a cohesive feel. The login page adds a looping cane-field video on
   top of that still, behind a frosted sign-in card.
