   CYSTEMS — Concept 6 "LIQUID"  ·  six.cystems.io
   Light editorial, molten liquid gold. Leads the Blueprints presale.
   Design language: reel-derived v2 (geometric sans + monochrome + gold).
   A distinct THIRD world: warm bone gallery/catalog vs EMBER (cool minimal)
   and OBSIDIAN (dark nocturne). Same brand family, different mood.
