     TYPE   : Bebas Neue = titles/identity ONLY. JetBrains Mono = everything else. No Inter, no third face.
     COLOR  : bg #000 · panel #0a0a0a · text #F5F5DC · dim #6b6b6b · hair #1a1a1a · edge #2a2a2a.
     ACCENT : LIME #A3FF12 = identity/title/active/primary value.  PURPLE #B612E5 = state/secondary/control.
              RED #FF2200 = punctuation ticks only ( // and > ).
     TITLES : every tool/page titled in Bebas + LIME. Labels in mono + dim, prefixed // or >.
     VOICE  : show, don't tell — titles + labels only, never explanatory paragraphs. */
