   SDM APU — Lockdown Screen
   Layar penguncian sistem. Muncul otomatis di index.html,
   portal.html, dan cv.html saat fitur Lockdown dinyalakan
   Super Admin. Semua pengguna kecuali Super Admin berhenti
   di layar ini.

   Palet mengikuti DESIGN.md:
     navy  #12294A / dark #0C1B33
     off-white #FAF8F4 / surface dark #15233D
     gold  #C9A24B (accent dark) / #8A5A1E (accent light)
   Aturan visual: 1px border bukan shadow, solid fill bukan
   gradient, radius 6px bukan pill. Semua motion dihentikan
   bila pengguna meminta reduced motion.
