/* ============================================================
   BURBLE LOGIN — the sign-in pages
   ============================================================
   Landing page, login, 2FA, password reset and registration: every
   page that common/public_redesign/login_header.php wraps. Loaded there
   before burble-core.css (tokens, reset, .bc-* components). These pages
   load no burble-admin.css.

   Moved out of burble-admin.css, which keeps its own copies of the
   shared rules (html/body, .help-block, .alert). Only the danger alert
   is styled here: it is the only one a sign-in page shows
   (two_factor_qr.js).
