   TABLE OF CONTENTS
   ==========================================================================
   1. Design Tokens (CSS Custom Properties)
   2. GeneratePress Overrides (colors, links, typography)
   3. Ad Slots (CLS-Safe)
   4. Article Cards & Section Grids
   5. Single Article (prose, labels, tags, social share, related)
   6. Sidebar Widgets
   7. Featured Carousel
   7b. Companies Table (/companies/ flagship page)
   8. Dark Mode
   9. Accessibility
   ==========================================================================

   ARCHITECTURE NOTE:
   GeneratePress (parent) owns: reset, layout containers, header, navigation,
   mobile menu, footer, comments, search. This child theme only skins those
   with tokens and adds SVJ-specific components. Keep it that way — structure
   belongs to the maintained parent, not to us.
