/* ==========================================================================
   qkohst.github.io — sistem desain
   Arah: tech gelap berlapis. Gelap adalah identitas utama; terang adalah
   pasangan yang dirancang setara, bukan sekadar kebalikannya.

   Prinsip:
   - Permukaan berlapis (bg < surface < raised), tiap lapis punya garis sorot
     1px di tepi atas agar terbaca sebagai bidang yang terangkat, bukan kotak.
   - Aksen ganda (biru -> violet) dipakai sebagai gradien dan cahaya, bukan
     hanya sebagai warna teks.
   - Metadata memakai monospace; angka memakai tabular-nums.
   - Easing eksponensial (.16,1,.3,1) memberi rasa berpegas tanpa pustaka.
