 *       height: 43px; padding: 0 30px; background-color: var(--jl-main-color);

 *       background-color: var(--jl-btn-bg) !important; }
 *   input[type='text'], … , textarea {
 *       outline: none !important; box-shadow: none !important; }
 *
 * The !important declarations beat ordinary class rules, which left every
 * button in this plugin as white text on a white card, painted them black on
 * hover, and removed the keyboard focus ring. These rules answer in kind and
 * are scoped to the plugin wrapper, so they cannot leak into the theme.
