/* ShiftNevis UI Tabs — canonical dashboard navigation patterns
 * Desktop-first, RTL-safe, and deliberately namespaced.
 *
 * Source of truth for primary tabs:
 *   Marketing / CRM top-level tabs (.crm-tabs).
 *
 * Usage:
 *   Primary/navigation tabs: .sn-tabs + .sn-tab
 *   Metric/filter tabs:      .sn-metric-tabs + .sn-metric-tab
 *
 * The CRM selectors are intentionally aliased here so the marketing reference
 * and every migrated dashboard screen consume one visual contract. Do not
 * recreate this pattern inside page-specific CSS.
