+## Модальные окна и UI
+
+### Модалки (modal.create)
+Система модальных окон реализована в `public/store/view/theme/dominik/assets/js/script.js` (объект `modal`, строка 64).
+
+**Вызов модалки с HTML-контентом:**
+```js
+modal.create({
+    modal: '<p>Содержимое окна</p>',  // HTML-контент (обязателен)
+    title: 'Заголовок окна',           // опционально
+    width: 400,                        // опционально, ширина в px
+    align: 'top',                      // опционально, прижать к верху
+    class: {                           // опционально, CSS-классы
+        'modal-body': 'p-0',
+        'modal-title': 'text-primary'
+    },
+    callback: {                        // опционально
+        show: function() { ... }       // колбек при показе
+    }
+});
+```
+
+**Загрузка контента через AJAX (modal.load):**
+```js
+modal.load(url, data);  // ожидает JSON-ответ с ключом 'modal'
+```
+
+### Выбор города в шапке
+Выбор города реализован через:
+- **Контроллер:** `public/store/controller/common/city.php`
+  - `index()` — отдаёт HTML-список зон (городов) для страны магазина
+  - `save()` — сохраняет `city_id` в сессию (`session->data['city_id']`), возвращает JSON с именем города
+- **Шаблон списка:** `public/store/view/theme/dominik/template/common/city_list.twig`
+- **Логика в хедере:** `public/store/controller/common/header.php` (строки с `model_localisation_zone`)
+  - Берёт `config_country_id` и `config_zone_id` из настроек магазина
+  - Если в сессии есть `city_id` — используется он, иначе `config_zone_id`
+  - Передаёт `current_city_name` и `city_list_url` в шаблон
+- **Кнопка в шапке:** `public/store/view/theme/dominik/template/common/header.twig` — после `{{ service_menu }}`
+- **JS-функция:** `citySelect(el)` в `script.js` — загружает список городов через AJAX, создаёт модалку, при клике сохраняет выбор в сессию и обновляет название на кнопке
+
