/* ============================================================
   Atlas auth page — shared styles for login + signup.
   Loaded by templates/account/auth.html (rendered for both
   /login and /signup). Mode-conditional layout via .auth-split--login
   vs .auth-split--signup on the split container; Alpine flips that
   class when the user toggles between login and signup inline.

   Built on 2026-05-04 by merging the original split inline
   <style> blocks of the (now-deleted) login.html / signup.html
   templates. Login chrome was the canonical base; signup-specific
   additions (.auth-checkbox*) appended.
