/* ============================================================================
   GVG / Gila Ventures Group — styles.css  (v1.0)
   Shared by the USA root page and the /mx page.
   Order: 1) fonts  2) tokens  3) base  4) layout  5) header  6) photo sections
          7) sections  8) components  9) footer  10) motion  11) responsive  12) print
   Font and image URLs resolve relative to /styles.css, so they work on /mx too.
   Palette is strictly grayscale: no blue, no accent color.
