/* tower-defense-shared.css — /games/tower-defense/lib/tower-defense-shared.css
 *
 * Geteilte CSS-Klassen die auf MEHREREN TD-Seiten gleichermaßen gebraucht werden:
 *   - Startseite (tower-defense.php)
 *   - Mobile-Spielseite (mobile/index.php)
 *   - Desktop-Spielseite (kommt in Schritt 2 dazu)
 *
 * Vorher waren diese Klassen byte-genau in tower-defense-start.css und
 * tower-defense-mobile.css dupliziert (Drift-Risiko bei späteren Änderungen).
 *
 * Lade-Reihenfolge: main-vhc.css → tower-defense-shared.css → seitenindividuelle CSS
 *
 * Enthalten:
 *   - 6 Akkordeon-Klassen (.td-accordion + Familie)
 *   - 2 Howto-Klassen   (.td-howto-section + Unterselektoren, .td-tower-icon)
 *   - 1 Sprach-Toggle   (.td-lang-switcher + Unterselektoren)
