   DEVEAPPS // TEMA GELAP — mengikuti gaya visual localhost/ciuc
   (CIUC Community Portal — "machine" aesthetic)

   Karakter yang ditiru:
   - Kertas gelap #09090a + grid merah sangat samar 42px, bukan overlay tebal
   - Tipografi sistem: Segoe UI untuk teks, Bahnschrift SemiCondensed untuk judul
   - Judul TIDAK huruf kapital, tracking rapat, bobot sedang (500)
   - Aksen merah #e32636 dengan glow sangat halus, bukan neon menyilaukan
   - Kontrol bersudut 2px, kontainer/kartu bersudut tajam 0
   - Garis pemindai berupa garis yang menyapu, bukan lapisan statis

   YANG TIDAK ditiru (permintaan pemilik): simbol salib apa pun.
   Reticle memakai kurung sudut — BUKAN crosshair silang.

   Semua aturan di-scope ke html.dark-mode, jadi tema terang tidak tersentuh.
