   NYX DESIGN SYSTEM v5.0 — Ephemeris
   Nyx is the Greek primordial goddess of Night. This identity is
   the moment night turns to day: a predawn violet-white paper,
   deep-indigo ink (the residue of night, not black), a luminous
   iris accent, and a single Venus-gold highlight — the morning
   star. Code lives in night panels. Display type is a literary
   serif (Fraunces): Nyx is a name from myth, and the serif earns
   that register while the mono keeps the technical voice.
   Same token names + selectors as before → /learn + /by-example
   inherit automatically.
