/**
 * Styling tambahan untuk layout admin (Bootstrap preset).
 *
 * Tujuan: menghasilkan tampilan dashboard modern dengan sidebar & topbar gelap
 * (terinspirasi gaya Metronic), tanpa mengubah komponen Bootstrap inti.
 *
 * Catatan:
 * - File ini hanya dipakai ketika preset UI = `bootstrap` atau `hybrid`.
 * - Untuk Tailwind/TailAdmin, gunakan styling dari build Tailwind (Vite).
