   THE SECOND ATMOSPHERE — styles.css
   ─────────────────────────────────────────────────────────────
   CANONICAL ARTISTIC DIRECTION: see MASTER_BRIEF.md
   "This is not a website. It is a living artwork."

   Design intent: deep space, cinematic stillness, minimal type.
   Typography is a whisper. Silence is part of the composition.

   Palette:
     --void          #000005              absolute space black
     --star          #ffffff              star / type white
     --atmo          #4fc3f7              physical atmosphere blue
     --dim           rgba(255,255,255,.38) subdued type
     --consciousness #d1daf0              second atmosphere neutral
                                          (cool pearl — no emotional state)

   Phase III colour slots (to be animated by JS emotional data):
     --emotion-primary    current emotional tint (default: pearl)
     --emotion-secondary  accent tint            (default: cool blue)

   Type:
     Display  — Cormorant Garamond 300 / italic  (elegance, geological slowness)
     Utility  — Inter 300                         (precision labels, nearly invisible)
