   auth-screens.css — redesigned logged-out auth experience (split layout).
   Self-contained (no Bootstrap/Velzon). All brand colors come from --brand-*
   CSS custom properties set inline on .auth-root from the DB-driven contract.
   High-fidelity to design_handoff_auth_screens. Works light only (auth is a
   pre-login surface); print is irrelevant.
