   Verde Optimal — shared stylesheet
   Retro-futuristic cyber-terminal. Brand accent tokens are verbatim from
   brand_assets/brand.md. Two deliberate departures from the guidelines: the dark
   ramp (--vo-void, --vo-surface-*) is a warm re-tint of brand "Dark Void"
   #000000, and body copy is set in Work Sans rather than brand-spec Montserrat —
   a warm humanist sans that softens the terminal tone. Roboto Mono still carries
   every heading, label and control. See the implementation notes in
   brand_assets/brand.md. Do not invent other colours or typefaces.
