   ELIX WEB — Bone paper (design handoff: "Elix Web.html")
   Warm bone ground · white paper sheets for posts and cards
   Lavender accent · sky secondary · deep-lavender signals ·
   citron highlight. All type rides on Noto Sans TC; mono carries
   handles, DIDs and structural labels.
   Light is canonical on :root; dark ("Ink") arrives from the system
   preference or an explicit scene theme.
