/* ============================================================================
   Lean CRM — design system
   Visual language matched to the Vuexy admin dashboard kit: a violet/indigo
   primary accent, pill-shaped active nav state, soft-tint status chips, and
   Public Sans throughout. Light theme is the base; dark follows the OS
   preference. Functionality/markup structure is unchanged — this file only
   restyles the existing components.
