   Homepage-specific styles. Loaded after site.css.

   Sections:
      1. Hero (Midnight, atmospheric, photo + meta grid)
      2. Generic .section shells (light)
      3. About (bio + facts panel)
      4. EXA framework section (Midnight, three pillar cards)
      5. Selected Work — case study list with elevation hover
      6. Global Teams (paper background, two columns)
      7. Credentials (paper cards row)
      8. Contact (Midnight, split layout)
      9. Layout utility classes
     10. Mobile (≤900px)
     11. Reduced motion

   Note: .cta / .cta-primary / .cta-secondary live in site.css with the
   dimensional treatment. Do NOT redefine them here — earlier versions of
   this file overrode them with a flat treatment that broke the elevation
   pattern on the homepage only.
