   Annota8 rebrand — login / auth visual styles
   Branch: rafiq_2026  •  Source design: rafiq-final-design (Phase 1+2)
   Scope: All visual tokens + layout for the auth surface (login, signup,
          password-reset, password-change). CSS-only — no new asset URLs
          beyond images/annota8-brand-logo.png referenced by user_base.html.
   Adds:  .annota8-auth__* layout, brand colour tokens, Hellix typography,
          light/dark theme variables (toggle wired in user_base.html),
          .form-wrapper / .text-wrapper classes used by all child pages,
          show/hide-password button styling (.annota8-auth__pw-toggle),
          decorative concentric ring backdrops.
   Replaces: legacy login.css. Selectors used by other pages (e.g.
             .lsf-input-ls, .lsf-button-ls) are preserved or extended,
             not removed, so any inline overrides still cascade.
   UNCHANGED: no Django settings, view, URL, JS bundle, or backend logic.
   Safe to revert: git checkout origin/nour_dev -- <this file>
