/* System C mock-up design system - base.
   Shared by every view: tokens (System C palette), the app shell and the component classes in
   src/design-system/components.md. Each view adds one theme file (patient.css, clinical.css,
   admin.css) that only changes tokens and the shell layout. The platform and Prototype Builder
   both load these files from /ds/, so a change here changes both. */
