/* ========== BEFORE / AFTER (modal popup) ==========
   Правила:
   * Оверлей занимает весь экран, центрирует панель, но если панель
     не помещается — уходит в скролл, а не вылезает за экран.
   * Размер панели — clamp(...) по ширине и высоте от viewport.
   * Учитываем env(safe-area-inset-*) на iOS и Android.
   * Stage 1:1 никогда не превышает min(viewport - headroom) — иначе
     object-fit: contain сжимает картинку, а overflow:hidden режет

/* ========== LIGHTBOX ==========
   Лайтбокс для просмотра полноразмерных изображений из истории.
   Архитектурно повторяет .cropper / .beforeafter: фиксированная
   подложка на весь viewport, затемнение, центрированная картинка,
   кнопка закрытия в верхнем баре.

   Особенности:
   * Полупрозрачный тёмный фон, мягкий fade-in.
   * Картинка адаптируется под viewport с object-fit: contain и
     max-height, чтобы ничего не обрезалось ни на десктопе, ни на
     мобильных.
   * Подпись (caption) и заголовок опциональны.
   * На мобильных: safe-area, уменьшенные отступы, более крупный
     тач-таргет на кнопке закрытия.
