/* ==========================================================================
   NexiBook Design System — Polish v2 (Admin Surfaces)
   Date: 2026-04-19
   Scope: tenant + trainer + superadmin + admin views (via header.ejs)

   Goal: visible, wow-ish refinement on 3 admin areas:
     1. KPI cards (.kpi-card) — larger values, cleaner spacing, softer shadow
     2. Sidebar (#tenantSidebar .sidebar) — pure CSS only, no HTML changes
     3. Activity feed (#activityFeed, .activity-feed-card)

   Rules:
     - CSS-only, zero HTML mutations
     - Targets EXISTING classes rendered by the app
     - Uses !important ONLY on visual properties that Bootstrap / legacy
       override with high specificity — never on layout/positioning that
       could break component behavior
     - Respects prefers-reduced-motion
     - Admin palette (indigo primary) wins via var(--color-primary)

   Load order: after polish-v1.css, via views/partials/header.ejs.
   To remove: delete this file + unlink tag from header.ejs.
   ========================================================================== */
