# Readiness fetches a tiny static page instead of searching. A `search` probe is
# a DuckDuckGo scrape every interval (1,440/day at 60s) from the same IP agents
# search from, which is how that IP ends up answering CAPTCHA. This proves the
# process and its outbound fetch path work, not that DuckDuckGo is answering.
