/* GC Consultants site, futuristic theme (Dylan's brief, Ben approved 2026-11-16).
   Near-black green base, mint glow from the GC logo leaf, Space Grotesk, a faint engineering grid,
   and the 3D facility model rendered on the same base colour so it sits in the page.
   The previous clean white theme is backed up in shots/gc-demeter-backup.css.
   Everything is scoped under .gc so the same sheet works inside the design canvas. */
