    const stations: Record<string, string> = {};
    for (const [code, info] of Object.entries(NABEL_STATIONS)) {
      stations[code] = `${info.name} (${info.canton}) — ${info.environment}`;
    }
    return JSON.stringify({
      count: Object.keys(stations).length,
      network: "NABEL — Nationales Beobachtungsnetz für Luftfremdstoffe",
