   SpaceTech AI — Front Page · "Orbital Mission Control"
   A spacecraft-HUD aesthetic: true-black void, luminous electric-blue + cyan
   instrument UI, JetBrains Mono telemetry labels, hairline instrument grid,
   gold reserved for a single vital highlight, generous negative space.

   EVERY selector is scoped under .stcai-landing so the blog/inner pages keep
   the cobalt "Deep Field Blue" system untouched. The neon palette is defined
   LOCALLY in the .stcai-landing scope below, overriding the global --stc-*
   tokens only on the front page. Web fonts apply only under .stcai-landing.
   Enqueued (handle "stcai-front") on is_front_page() only.
