/*!
 * chat.css — макеты Svitex Chat (рабочий мессенджер экосистемы Svitex).
 * Подключать ПОСЛЕ ../svitex-erp-ui/svitex-erp-ui.css и ../svitex-disk/disk.css:
 * токены, .ghost/.svx-primary/.seg/.chip/.svx-err, .dk-top/.dk-iconbtn/.dk-ava/.dk-search/.dk-menu/.dk-empty/.dk-tabbar/.dk-auth/.dk-scene — оттуда.
 * Здесь только .ch-* (компоненты чата). Новых цветов нет: только токены --svx-* / --ink / --muted / --line.
 * Единственная заливка-акцент — --ink (#2B2B2B, в тёмной теме #EDEDED). Ошибки — иконка + тёмный текст + пунктир, без красного.
