/*
 * assets/css/cai-blocks.css — стили библиотеки компонентов inc/cai_blocks.php (префикс .cai-).
 *
 * ЧТО:   внешний вид всех блоков cai_*: лайтбокс, видео-петля, вьюер, до/после, лупа, лента, шаги,
 *        карточки, кейсы, отзывы, прайс-пикер, три круга, полоса фактов, FAQ, защищённый ролик.
 * ЗАЧЕМ: новые страницы Collager.ai (главная «AI Collage Maker», /photo-mosaic-maker/), октябрь 2026.
 * КАК:   подключает cai_blocks_assets('css'); можно и include внутрь <style>, как index.php делает с
 *        остальными файлами assets/css. Перенесено и переписано с css_internal/article.css CollageBerry.
 * ИНВАРИАНТЫ:
 *  - стиль сайта: Lato — текст, Raleway — заголовки, акцент #ff2b4e, кнопки .button сайта (40 px,
 *    заглавные, жирные) — повторены в .cai-btn, чтобы блок не зависел от порядка подключения CSS;
 *  - 320–1400 px, ничего не шире экрана: ленты листаются внутри себя и с кнопками; у сенсорных
 *    кнопок не меньше 44 px (у вьюера 56 px с зазором 14 — правило OSD);
 *  - touch-action: none — ТОЛЬКО на ручке «до/после» и на холсте вьюера в режиме просмотра;
 *    на контейнерах — pan-y, иначе палец по картинке перестаёт листать страницу;
 *  - у элементов, которым задан display, правило [hidden] перебито явно (иначе hidden не работает).
