/*
  Nocturne — c2 visual world (Claude doorway, 05.08 build)
  THESIS: a warm, dark "AI console" — near-black warm charcoal, an amber-orange
          glow, monospace chrome, and an authored Claude Code terminal (a prompt
          and a streaming reply) as the signature object. A power-user's manual,
          distinct from c1's warm-light explainer.
  OWN-WORLD: warm near-black (#141013), soft warm-white text (#eee6dd), amber
             orange (#f0864a / #f7a56b) on CTAs and the cursor, a quiet teal for
             the up-state. Monospace for chrome, clean sans for prose.
  MOTION: one authored moment — the terminal cursor blinks on load.
