/* ==========================================================================
   Registration — two-column sign-up

   Colours, ambient light, brand, language picker and buttons live in
   auth-theme.css, which follows the Theme mode chosen in Business Settings.
   This file only lays the registration page out, using those tokens.

   Left is a sticky rail carrying the headline and the step list; right is the
   form. register-split.js steps through the numbered sections and sets
   --reg-pct / --reg-frac on <html> for the progress lines.

   Class names inside the two partials (reg-section, reg-nature-*) and the
   Bootstrap markup they emit are unchanged; this file restyles them.
