/* ------------------------------------------------- YAN MENULU DUZEN (103)

   Kullanici bildirdi: *"mobil gorunumde /grup/... sayfalari bozuluyor sol
   menuden dolayi."* Olcum: 375px'te `documentElement.scrollWidth` 681,
   `clientWidth` 375 -- sayfa 306px yatay tasiyordu. Kolonlar 250px + 383px
   olarak KALIYORDU.

   SEBEP `.grid`in kendisi degil: `urunler.twig` kolonlari SATIR ICI
   `style="grid-template-columns:250px 1fr"` ile veriyordu. Satir ici bir
   bildirimi hicbir MEDYA SORGUSU ezemez (`!important` olmadan) -- yani o
   sayfa duyarli OLAMAZDI. Panelde ayni hata daha da acikti: uc sablon
   `class="grid-2"` yaziyordu, yani yazan kisi 900px'te cokmesini
   ISTIYORDU, ama satir ici bildirim o niyeti sessizce iptal ediyordu.

   BU YUZDEN KOLONLAR OZEL DEGISKENDEN GELIYOR: satir icinde yalnizca
   `--yan-sol`/`--yan-sag` kaliyor, `grid-template-columns` STIL
   DOSYASINDA tek yerde duruyor ve medya sorgusu onu ezebiliyor. Satir ici
   bir ozel degisken de kazanir -- ama medya sorgusu degiskeni degil
   BILDIRIMIN TAMAMINI degistirdigi icin onemi kalmiyor.

   Tek sinif + tek cokme kurali BILINCLI. Uc sayfa icin uc ayri sinif
   yazsaydim, dorduncu sayfa eklendiginde medya sorgusuna eklenmesi
   unutulacak bir LISTE olurdu -- bu projede "elle yazilmis liste
   kaynaktan kayar" dersi bes kez odendi. Kural sinifin kendisinde.

   `_test_stil.php` iki seyi olcuyor: (1) hicbir sablonda satir ici
   `grid-template-columns` yok, (2) `.yan-duzen` tanimlayan her stil
   dosyasi onu bir `max-width` medya sorgusunda cokertiyor. Ikincisi
   olmasa sinif "duyarli gorunen" ama cokmeyen bir sey olabilirdi.    */

       Olcum: 375px'te `.burger` 376px'ten basliyordu -- yani mobil
       menuyu acan TEK dugme gorunur alanin disindaydi ve sayfa 41px
       yatay tasiyordu. `/grup/...` dahil BUTUN vitrin sayfalarinda.

       Sebep: `.brand` ve `.header-actions` ikisi de `flex: none`. Ikisi
       de kucuvlemiyor, toplam genislik kapsayiciyi asinca fazlasi sagdan
       tasiyor -- ve `.header-actions` sonda oldugu icin tasan o oluyor.

       102 bunu KOTULESTIRDI: marka yazisi "Kart Merkezi"den
       "RFIDIMALAT.com"a cikti (800 agirlikta iki karakter daha) ve alt
       satir uzadi. Isareti o degistirme koydu, sebebi bu kural.

       Cozum kucuvlemeye izin vermek: marka esner ve gerekirse ucu
       kirpilir; dugmeler `flex: none` KALIR -- tiklanabilir bir hedefin
       kucuvlemesi onu kullanilamaz yapar.                             */
