Jedes Windvorranggebiet kann jetzt 1–n text_fragment-Einträge als Stellungnahme-Kriterien referenzieren. Das Panel lädt diese lazy beim Öffnen und zeigt sie als aufklappbare Accordion-Sektion. Außerdem: alle hardcodierten Strings im Karten-Block (Panel, Map, Block) durch t()-Aufrufe ersetzt; 7 neue Translation-Keys ergänzt. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
