   servis kılavuzu sayfası. Numaralı bölümler, mono alan etiketleri, leader
   çizgileri, iş emri formu ve mühendislik çiziminin antet bloğu.

   KAPSAM KURALI: yukarıdaki 1–11. bölümlerden hiçbir kural ya da token
   değiştirilmedi. Buradaki her şey yeni `.dx-*` sınıfları altında yaşar;
   diğer 9 sayfa bu bloktan etkilenmez. Anasayfaya özgü olduğu için birkaç
   paylaşılan sınıf (`.fault-picker`, `.faq-item`, `.independence-note`)
   `.dx-form` / `.dx-faq` / `.dx-note` sarmalayıcısı altında ezilir.
