/*
  Pywa Cloud — design system
  --------------------------------------------------------------
  This file is the shared visual language for Pywa Cloud: the marketing
  site today, the dashboard eventually. Dark foundation, restrained
  WhatsApp-green accent, monospace used as a design material (labels,
  status, diagrams) rather than only for code. No framework, no build
  step — plain CSS custom properties so any of this can be lifted into
  the dashboard's own stylesheet later without translation.
