Describe cookieExpiresAt as an expiration time.

The implementation stores cookieExpiresAt as Date | null. The phrase “reflects the cookie” can imply that the property contains the cookie itself. State that it represents the current expiration time of the client authentication cookie used by Device Trust to recognize a known browser.

Proposed wording

The implementation stores cookieExpiresAt as Date | null. The phrase “reflects the cookie” can imply that the property contains the cookie itself. State that it represents the current expiration time of the client authentication cookie used by Device Trust to recognize a known browser.
