/* Akar masalah sidebar tidak bisa discroll:
   .rp-sidebar adalah flex column setinggi viewport (position: fixed + inset),
   tetapi daftar menu duduk di dalam <nav> yang bukan flex item ber-aturan.
   <nav> itu anak flex sidebar dan secara default `flex: 0 1 auto` +
   `min-height: auto`, jadi ia tidak menyusut di bawah tinggi konten menu — ia
   justru memanjang dan MEMBUAT SIDEBAR melewati batas viewport. Akibatnya
   `.rp-nav { overflow-y: auto }` tak pernah aktif (tingginya selalu = tinggi
   konten) dan menu paling bawah seperti "Paket Les" untuk admin terpotong
   tanpa bisa discroll.

   Perbaikan: <nav> dibuat flex item yang benar-benar mengisi sisa tinggi
   (`flex: 1 1 auto` + `min-height: 0`) dan menjadi flex column, sehingga
   `.rp-nav` di dalamnya mendapat tinggi terbatas dan scrollbar-nya bekerja.
   `min-height: 0` di KEDUA tingkat itu wajib, bukan hiasan: nilai `auto`
   (default) mencegah flex item menyusut di bawah tinggi kontennya dan
   membuat overflow tak pernah terpicu. */
