   28. Topbar açılır panelleri — lokasyon seçici & kullanıcı menüsü
   --------------------------------------------------------------------------
   Ortak iskelet (`.dd-*`) static/js/app.js içindeki `App.dropdown()`
   yardımcısıyla birlikte çalışır:

     .dd-wrap      konumlandırma çıpası (position: relative)
     .dd-panel     panel; `.is-open` ile görünür, `.dd-flip-start` ile sola
                   çevrilir, 576px altında alt sayfaya (bottom sheet) döner
     .dd-handle    alt sayfa tutamacı (yalnız 576px altında görünür)
     .dd-head      panel başlığı        .dd-search  panel içi arama
     .dd-scroll    kaydırılabilir gövde .dd-divider ayraç
     .dd-section   bölüm başlığı        .dd-group   bölüm sarmalayıcı
     .dd-item      menü satırı          .dd-option  listbox satırı
     .dd-foot      alt şerit (çıkış)

   Panel yarıçapı/kenarlığı/gölgesi `.app-card` ile aynı token'ları kullanır.
   Geçişler kısa (.16s) ve `prefers-reduced-motion` genel kuralıyla kapanır.
