   [v640] SATIŞ KÜMESİ — ORTAK TASARIM SİSTEMİ
   Mehmet'in SEO alt sayfa spec'i §10: "Her sayfa mevcut XYZ design system'i,
   header/footer ve CTA akışını yeniden kullanmalı."

   Bu dosya /satis/ ALT SAYFALARI içindir (musteri-itirazlari, satis-gorusmesi-
   adimlari, musteri-turleri…). /satis/index.html kendi gömülü stilini korur —
   ana sayfanın yayın hâlini riske atmamak için ona dokunulmadı; buradaki
   değerler onunla BİREBİR aynıdır (renk değişkenleri, tipografi, kart dili).

   🔴 Spec §10 yasakları: stock fotoğraf yok · "SaaS feature card duvarı" yok ·
   ağır animasyon yok (CWV). Her sayfa kendi görsel metaforunu kendi
   <style> bloğunda tanımlar; ortak iskelet burada durur.
