  Theme: GENESIS Expression (gen-exp)
  Description: Syntax-highlighting theme for the ICONICS GENESIS 64 expression language (gen_exp).
               Colours are sourced directly from the GENESIS 64 Expression Editor rendering pipeline.
  Maintainer: ICONICS Technical Documentation
  Colour source reference (Color.FromArgb values):
    UnaryOperator / BinaryOperator / Function / NumberValue → rgb(0,0,0)       Black
    StringValue                                                 → rgb(128,0,0)     DarkRed   (string/char literals only)
    BooleanValue / If / Then / Else                         → rgb(0,0,255)     Blue
    Variable / AliasValue / Flare {{}} tags                 → rgb(0,128,128)   DarkCyan  (user override: point names unified with variables)
    Comments and type-cast names have no entry in the source; editorial defaults are used.
