/* ============================================================================
   AUTH FLOW - Blueprint Authentication Interface
   ============================================================================

   Design: Matches Admin/Provider Blueprint aesthetic
   - Blueprint grid background with amber tint (auth identity)
   - Corner bracket markers
   - JetBrains Mono + DM Sans fonts (consistent with portals)
   - Amber accent for auth (neutral - not cyan/green which are portal-specific)
