 * TBY musteri istegi (2026-05-27 son revizyon):
 *  - Split layout iptal; eski overlay tasarimi geri ("yazilar gorselin
 *    ustunde", "gorsel dikey uzunlamasina ve enlemesine yer kaplayacak").
 *  - Tek viewport / scrollsuz korunur (body.is-home + footer gizli).
 *  - Hem mobile hem desktop ayni pattern: tam-ekran arka plan gorseli
 *    (object-fit:cover ile her iki yone yayilir), uzerinde alt-koyulasan
 *    scrim ve ortalanmis overlay copy (brand + intro + CTA, beyaz).
 *  - Gorsel: /images/dekor-kompozisyon.webp (1636x2048 dikey). Manifest'te
 *    [480, 768, 1024, 1440] + orijinal 1636 srcset varyantlari mevcut →
 *    tarayici viewport+DPR'ye gore max kaliteli varyanti secer ("kaliteyi
 *    dusurmeyecek olcude buyur"). */
