/* =============================================================
   AVIATION · Gosu Upskill
   Industry landing page — bright/white body with dark "punch"
   bands, same glass + cinematic system as Oil & Gas. The page
   reads light; tokens re-scope per colour zone so cards flip
   between dark-on-light (light zones) and light-on-dark (the
   Numbers/Skills/Games band + the Delivery/Process/CTA close).
   Accent = avionics cyan ("glass cockpit at altitude"), the first
   cool-accent page in the family. Because the shared base.css bakes
   a few amber values into the process timeline, those are overridden
   to cyan at the bottom of this file.
