/*
 * UniDoc UI redesign — dialogs and panels (CSS-only, reversible).
 *
 * Loaded after ui-ios.css. Restyles the remaining Word-era dialogs with the
 * same iOS language as the ribbon: grouped grey sheet, white rounded rows,
 * hairline separators, filled inputs, one system-blue accent, round close
 * buttons. Shell chrome only: no DOM, id or behaviour changes, and no
 * document/page variables are touched. Removing the <link> reverts it.
