/* Sovran_SystemsOS Hub — Web UI Stylesheet
   The Hub redesign — softer dark theme, GNOME 50 / libadwaita surfaces,
   Sovran green reserved for status and actions.

   Design tokens are defined once here. Legacy variable names from the
   previous theme are aliased to the new values so every stylesheet
   (support, security, domain-setup, onboarding, …) re-skins without
   needing per-rule edits. */
