   Apex Evergreen Pharma — R&D & CRO Page Styles
   --------------------------------------------------------------------------
   Self-contained page styles. Consumes tokens from design-system.css and
   builds on global.css. Redefines the shared components (reveal, node-divider,
   media-frame, orbital-node icons) with identical values so this page looks
   like the same site without loading home.css.

   Sections:
     1. Hero   2. Integrated journey   3. R&D / discovery
     4. CRO    5. Integrated advantage   6. Closing CTA
