/* ==========================================================================
  Red Valkyrie — Design System (CSS)
  File: design-system.css

  Goals:
  - Fast, pure-HTML multi-page site
  - Conversion-first layout primitives and components
  - A "modern 2025+" feel: bento grids, subtle motion, high-contrast typography
  - Maintainable: tokens + composable components

  Page interaction philosophy:
  - Consistent header/footer across all pages
  - Services pages share the same hero + section patterns
  - Case studies reuse the same "card--case" and "stats-grid" blocks
  - Optional: View Transitions API makes multi-page navigation feel app-like

  Implementation notes (for you + future edits)
  - Service pages should reuse:
      .hero (or a lighter hero), .bento-grid for deliverables, .faq, .cta-box
  - Case study pages should reuse:
      .stats-grid for metrics, .card--case, .cta-strip for next step
  - Keep the top nav identical across all pages for familiarity + conversion.
