/* Public tool pages (/tools - tools.php, /tools/<slug> - tool.php). The
   widget markup (tools-lib.php) is shared with the dashboard, whose dark
   look is dash.css; here it sits in a .cf-tool panel on the light site.
   Bootstrap's .input-group is a flex row - the widgets use it as a plain
   label-over-field block, so it's reset inside .cf-tool. */
