   Raven Tech v2 — Visual Language
   ------------------------------------------------------------
   v1 was a dense, Apple-flavored trading desk. v2 is an AI
   brain console: obsidian + electric cyan/violet, generous
   negative space, hairline borders that *glow*, and motion
   that suggests live thinking.

   Anyone glancing at this UI should know in <2s it is v2 tech.
