   DESIGN TOKENS
   Palet   : hijau tua zamrud (utama) + kuning tembaga/emas (aksen)
             di atas latar gading lembut — dipilih untuk menghadirkan
             suasana tenang & khidmat yang relevan dengan tema ibadah.
   Tipografi: Spectral (judul, serif bermartabat) + Inter (isi, netral,
             mudah dibaca di layar kecil) + Amiri (khusus teks Arab).
   Signature: navigasi "tasbih" — untaian bulatan bertautan sebagai
             representasi visual dari urutan gerakan sholat.
