 * K-code App Common CSS
 * ------------------------------------------------------------
 * Purpose:
 * - Standalone K-code web apps such as /masume-app/ can use the
 *   same app button design as the WordPress site without loading
 *   the full custom_main.css.
 * - Keep this file limited to app-common UI parts.
 *
 * Source basis:
 * - Extracted and minimized from custom_main.css button definitions.
 * - Added shared appbar utility buttons for Help / About.
