Cookie policy for essential site preferences.

This site uses a small essential preference so the cookie notice does not appear on every visit after acknowledgement. That preference supports a cleaner browsing experience and does not create a public account.

The site is designed to work without advertising cookies. If analytics are used, they must remain privacy-conscious and should measure aggregate website performance rather than individual visitor behavior.

Browser settings can clear cookies and local storage. Clearing storage may cause the notice to appear again. Some embedded services, including the map on the contacts screen, may apply their own technical handling under their own terms.
