/*
 * Dark Empires — Main shared stylesheet for all public pages.
 *
 * This file consolidates the old common stylesheets
 * (variables, base reset, header, navigation, telegram button)
 * into a single file so every public page looks consistent
 * and loads fewer CSS files.
 *
 * Pages should include this file first, then one page-specific stylesheet.
