/*
 * Knowledge base article styles (Issue #4384).
 *
 * A global stylesheet rather than a component's .razor.css on purpose: the article body is
 * stored HTML rendered through MarkupString, and Blazor's CSS isolation only scopes elements
 * the component's own markup creates. The same rules style the customer article page, the
 * admin editor and its preview, so what the editor shows is what the customer sees.
