   Argos — pre-alpha teaser site
   Palette is pulled straight off the key art: torch-flame amber, warm cave
   stone, and a near-black earth-shadow ground. Forked from cebus-vr's
   styles.css (Web/cebus-vr/static/styles.css) — same structure, different
   color story. Keep layout rules in sync between the two; palette is the
   one thing that should stay different.
