/* Tukangin.id design system
   Struktur editorial dipinjam dari template kaitex.id: kertas, tinta hitam, judul ringan.
   Identitasnya dari bengkel las kanopi:
   - Aksen tunggal = merah meni (cat dasar anti karat yang dioles ke besi sebelum dicat akhir).
     Dipakai untuk garis las, penanda aktif, dan blok survei saja.
   - Penanda blok = potongan miring seperti profil atap kanopi, pengganti kotak hitam kaitex.
   - Archivo (punya sumbu lebar) untuk wordmark dan teks: bentuk lebarnya terasa seperti profil baja.
     Lexend light untuk judul supaya kontras dengan wordmark yang tebal. */
