+// Erzeugt eine PDF-Tabelle aller BEOs mit Wohnort und Straßenentfernung (km)
+// zur Sternwarte Welzheim — zum Versand an die BEOs zur Verifizierung.
+//
+// Daten kommen über den PHP-Proxy (cmd GET_BEOS). Das HTML wird mit Headless-
+// Chrome nach PDF gerendert.
+//   node --env-file=.env erzeuge-pdf.mjs
+//
+// Ergebnis: beo-entfernungen.html und beo-entfernungen.pdf
