/* ==========================================================================
   GUBAH HUB — DESIGN SYSTEM "PROOF & REGISTRATION"
   Kosakata komponen: sheet (halaman), frame (border luar), slug (baris
   metadata mono), folio (nomor mono), control bar (colorbar), register mark
   (crosshair), crop mark (siku sudut), trim (batas konten), proof slot
   (bidang foto — belum dipakai, GubahFoto di luar scope).

   Prinsip: struktur > dekorasi. Aksen itu langka. Bidang, bukan kotak
   bertumpuk. Setiap elemen non-teks harus punya alasan pre-press.

   (b) bidang dominan — Foto memakai proof slot sebagai bidang utama sheet,
   (c) crop mark dipakai di showcase; register mark tetap milik sudut frame.
