/* =====================================================================================================
   OpenBuilds CAM design system
   -----------------------------------------------------------------------------------------------------
   One place for the visual language: tokens (colour, type, spacing, radius, elevation, motion) for the
   light and dark themes, and the styling of the shared components (buttons, fields, menus, dialogs,
   notifications, tabs, trees, scroll bars).

   Scope: everything is under html[data-ds]. The legacy stylesheets (Metro UI, css/themes/dark.css) use
   high-specificity and !important rules; the extra attribute lets these rules win predictably without
   piling on overrides. Remove data-ds from <html> to fall back to the legacy look.

   Feature/layout styles (panels, operation list, measure box...) live in css/ui-refresh.css and use
   these tokens.
