/* ============================================================
   CryoLynx — Authentication pages (login / register /
   forgot password / reset password).

   Shared on purpose: the four auth views have Layout = null, so
   anything written inline in one of them has to be copy-pasted
   into the other three and then drifts. Keep the design system
   here and let the views stay markup-only.

   Loaded AFTER main.css. scripts.js injects the active dore
   theme stylesheet *before* main.css (see loadStyle()), so
   everything in this file already outranks the theme in the
   cascade — no !important needed except where dore uses inline
   or id-level rules.

   Palette matches the modernised home page (Views/Home/Index).
