   GhostVoice — Design system
   --------------------------------------------------------------------------
   Palette  : near-black blue surfaces, electric-blue primary, cyan "sonar"
              accent (locked to the brand spec).
   Display  : Alexandria  — geometric Arabic+Latin sans; the headlines finally
              render with real character instead of the OS fallback.
   Body     : Rubik       — Arabic/Latin harmony, slightly warm.
   Data     : JetBrains Mono — license keys, IDs, tech labels.
   Wordmark : Space Grotesk — the Latin "GhostVoice" brand only.
