/* =========================================================================
   GEO SOLUTIONS — HOMEPAGE v4.1 (Altrum pixel-by-pixel hero)
   Generated: May 2026
   Depends on: tokens.css, base.css, components.css, layout.css

     - Full viewport with abstract warm gradient background
     - Top tag: "©Growth · Engineering · Operations"
     - MEGA wordmark "Geo™" (clamp up to 14rem) with TM superscript
     - Right column: 5 numbered services with dotted dividers
     - Bottom-left: tagline + "Scroll to explore" cue
     - Bottom-right: glass "Let's Talk" card with logo avatar
     - Plus icons in 4 corners (decorative)

   Post-hero sections preserved from v4.0 with light Altrum-flavor adjustments
