/*
 * Kategori filtre paneli - TEK TASARIM KAYNAGI (kamis + makine).
 *
 * NEDEN AYRI DOSYA (Tailwind utility'leri yerine):
 * Tailwind v4 sinif taramasini DERLEME aninda yapiyor ve public/build/ icindeki
 * derlenmis CSS elle uretiliyor. Blade'e bugun yeni bir utility yazilirsa
 * (ornegin "sticky bottom-0") derleme yenilenmedikce o sinif CSS'te YOK ve
 * sessizce etkisiz kaliyor. Panelin govdesi bu yuzden derleme gerektirmeyen
 * duz CSS; public/js/*.js dosyalari gibi dogrudan servis ediliyor.
 *
 * Yerlesim sozlesmesi: .cf-panel bir FLEX SUTUN'dur.
 *   .cf-head  -> sabit yukseklik
 *   .cf-body  -> kalan alan, kendi icinde kayar (overflow-y:auto)
 *   .cf-foot  -> panelin altina yapisik ("ARA" butonu)
 * Panel yuksekligi masaustunde ekran yuksekligine kilitli oldugu icin buton
 * filtre ne kadar uzarsa uzasin EKRANIN ALTINDA kalir; kisa filtrelerde ise
 * dogal olarak listenin hemen altindadir.
