/*
  Layout: an orrery seen at astronomical twilight. One fixed WebGL sky sits behind a long, left-aligned editorial scroll.
  The page itself is one lunar month: eight chapters, eight phases (right-edge navigator). The 3D sky changes scene per chapter:
  the golden-ratio mark assembling from its own circles, a real lit moon whose phase follows the reader, and the 19-year Metonic ring.
  Everything else stays quiet: no cards, no fade-ins, no tilt, type and space only.
