Thank you for the response - but I'm asking a very basic question:
Does allowing cookies from a specific site allow cookies from "subsidiary" sites?  Same question when blocking cookies.

It depends on how the cookie is created. From https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie:

Domain=<domain-value> Optional
Specifies those hosts to which the cookie will be sent. If not specified, defaults to the host portion of the current document location (but not including subdomains). Contrary to earlier specifications, leading dots in domain names are ignored. If a domain is specified, subdomains are always included.

If you allow cookies from yyy.zzz and a cookie is created without the optional "Domain" parameter cookies from xxx.yyy.zzz are not allowed. They ARE allowed if the Domain is specified.
