/* ==========================================================================
   TEMA "FLAT GRAYSCALE" — datar, tanpa warna, tanpa hiasan.
   Aktif bila <body class="theme-flat"> (diatur dari Identitas Perusahaan).

   Prinsipnya: satu-satunya pembeda antar elemen adalah NILAI ABU (terang/gelap)
   dan garis tipis. Tidak ada gradien, tidak ada bayangan menggantung, tidak ada
   sudut membulat besar. Warna dibuang seluruhnya — termasuk hijau/merah semantik
   Bootstrap — sehingga makna dibawa oleh label, ikon, posisi, dan ketebalan.

   Gambar & grafik di-grayscale lewat filter pada elemennya sendiri (img/canvas),
   BUKAN pada pembungkus: filter pada leluhur membuat elemen position:fixed
   (modal Bootstrap) berpindah acuan dan tampil melenceng.
