 * Tool Content CMS — modern presentation layer
 * ----------------------------------------------------------------
 * Scoped entirely under .tcms (only present on CMS-rendered tool
 * pages — see app/tool_content.php). Never touches:
 *   - legacy static tool pages (they don't have this class),
 *   - the widget's own internals (#tool-widget/#ut-widget/#tool-root
 *     children keep whatever markup tn-runtime/ut-runtime/engine.js
 *     generate, styled by their own tn/ts/ut stylesheets — this file
 *     only styles the editorial chrome AROUND the widget).
 * Reuses the design tokens already defined by whichever engine
 * stylesheet (tn or ts) is loaded for this tool, so it adapts to the
 * site's configured brand colors automatically.
