+	Controls the interaction with the QRZCALL.EU Premium XML API.
+
+	QRZCALL.EU is a QRZ-compatible callsign database. Its XML feed
+	(/v1/pub/callsign_xml.php) returns the same field names as QRZ.com so
+	this library mirrors the QRZ.com integration almost identically — but
+	uses a single long-lived Personal Access Token (PAT) instead of a
+	callsign/password → session-key dance.
+
+	Users generate a PAT at https://qrzcall.eu/ → My Profile → Account →
+	API Tokens. In Cloudlog they select "QRZCALL.EU" as their Callbook
+	Provider in Account Settings and paste the PAT into the Callbook
+	Password field (stored encrypted, per user, like the QRZ password);
+	the Callbook Username field is left blank. The library sends the PAT
+	as "Authorization: Bearer pat_…" on every lookup. Tokens are revocable
+	per-logger, so a compromised Cloudlog install can be locked out
+	without disturbing other clients.
+
+	Access tier: PAT generation requires a Data or Extra subscription on
+	QRZCALL.EU. The library doesn't need to know about subscription state —
+	the upstream endpoint enforces it and returns 401/403 if absent.
+
+	Sign-up + token UI: https://qrzcall.eu/
