/* =====================================================================
   NORTHBRIDGE FINANCIAL REVIEW — MAIN STYLESHEET
   ---------------------------------------------------------------------
   Design language: editorial "print masthead" publication, not a
   marketing landing page. Deep navy + ivory + brass accent, serif
   display type paired with a clean sans body face, hairline rules
   borrowed from newspaper layout conventions.

   Table of contents:
     1. Design tokens (custom properties)
     2. Reset & base
     3. Typography
     4. Layout helpers
     5. Utility bar & masthead & nav
     6. Buttons & forms
     7. Cards (article cards, author box, pull quotes)
     8. FAQ accordion
     9. Footer
     10. Page-specific (hero, breadcrumbs, tables, callouts)
     11. Responsive
     12. Accessibility & motion
