/* Suppress the WebHelp theme picker — production Oxygen WebHelp overlay.
 *
 * The publication ships dark, full stop (issue #173): the reader gets no
 * light/dark choice, so the control that offers one is removed from view.
 * dark-mode.js pins the theme; this file removes the only affordance in the
 * published output that could unpin it.
 *
 * Oxygen renders the picker as
 *
 *   <div class="wh_theme">
 *     <button id="wh_theme_button" class="wh_theme_btn" data-wh-theme="auto" …>
 *   </div>
 *
 * in the header of every page type, and topic.js appends the Auto / Light /
 * Dark dropdown items (#webhelp_theme_auto, #webhelp_theme_light,
 * #webhelp_theme_dark) into that wrapper on first click. Hiding the wrapper
 * therefore takes the button and the menu with it.
 *
 * Self-contained, like the sibling overlays. Install per ../README.md (copy
 * into your publishing template's resources/ and reference it from the .opt
 * <resources> so it loads last and wins the cascade).
