/* ============================================================
   EdgeStacker — shared auth form language
   One stylesheet for every logged-out page: the centered card,
   the field pattern (label / input / error), the banner variants,
   buttons, and the footer switch line. Django renders the same
   markup server-side; error/notice states are toggled by adding
   the matching class or block, not by JS.

   Loaded on top of tokens.css (all colors/radii/shadows come from
   there). Source of truth: docs/design_handoff/auth/auth.css.
