/* ============================================================
   Окно потери связи — Components/Layout/ReconnectModal.razor и модуль js/reconnect.js.

   Все правила под .tb-reconnect: у оверлеев и дока для OBS свой элемент с тем же id
   #components-reconnect-modal, и эти стили его задевать не должны.

   Состояние — атрибут data-state на диалоге. Видимость — data-open: js ставит его кадром позже
   showModal() и снимает перед close(), поэтому окно и подложка и проявляются, и гаснут плавно.
   Тексты, значки и кнопки всех состояний лежат в разметке сразу; js помечает подходящие
   к состоянию атрибутом data-active.
