/* =========================================================
   CRENOE — sistem desain situs
   Satu berkas untuk semua halaman. Sebelumnya tiap halaman
   menyimpan salinan CSS-nya sendiri: nav byte-identik di 8
   berkas, footer di 7, dan itulah kenapa /tools perlahan
   menyimpang dari halaman depan tanpa ada yang menyadari.

   Token disalin PERSIS dari static/style.css milik aplikasi,
   termasuk urutannya: gelap adalah :root, terang adalah
   penimpaan. Pemicunya saja yang beda — di app lewat
   [data-theme], di sini lewat preferensi OS, karena situs
   pemasaran tidak punya tombol tema.

   ATURAN BRAND yang ikut dibawa: lime tidak pernah jadi TEKS
   di latar terang (kontras 1,33:1). Status aktif memakai lime
   sebagai BIDANG dengan tinta --on-brand. Untuk kasus langka
   yang memang butuh teks selime, pakai --brand-ink.
