 * Base URL of the AppView used for all public read operations (engagement,

 * can be swapped in without code changes. Note this is a structural dependency:
 * likes/reposts/thread aggregation only exists in an AppView, so content
 * outside the configured AppView's crawl is invisible to FlockOff regardless
 * of which PDS the logged-in user is on.
