/* Styling for the shared DataTable component.
 *
 * Loaded globally from App.razor. Every selector is prefixed `dt-` AND scoped
 * under the component's `.dt` root. The extra class in the chain is not
 * cosmetic: host pages style bare elements inside their own root (see
 * `.edp-worker table`, `.edp-worker button`, `.edp-worker th, td` in
 * edp-worker/worker.css), and those stylesheets are linked from <HeadContent>,
 * i.e. after this one. A tie on specificity would therefore be lost — the rules
 * below have to win outright.
