 * sdamp.synlink — Shared lightbox CSS companion (task 17 extract).
 *
 * Эти правила нужны на любой странице, где shared sdamp-lightbox.js создаёт
 * DOM-элементы (.lb-controls / .lb-card / .lb-blur-bg / .lb-toast) в body
 * после открытия GLightbox. До task 17 правила жили в copy-paste form в
 * album.detail/templates/.default/style.css и album.embedded/templates/.default/style.css.
 * На /gallery/ (task 17 C1 — fs-btn tile-lightbox) ни один из этих стилей
 * не подгружался → controls получали site-template default (красный pill close,
 * raw caption HTML без структуры).
 *
 * ВНИМАНИЕ: до полного refactor дублирующие правила остаются и в
 * album.{detail,embedded}/style.css — безвредно (одни и те же правила, Bitrix
 * Asset дедуплицирует подключение этого файла). Backlog: удалить дублирующие.
