    # while reporting `healthy` and returning ZERO results for every query,
    # because SearXNG engine scrapers rot as upstream sites change their markup
    # and the project ships near-daily releases to keep up. `docker compose pull
    # && up -d` is the update; scripts/searxng-health.sh is what tells you it is
    # needed, because /healthz cannot.

    # ⚠ `--tries=1` MUST keep its `=1`. Written as two argv entries
    # (`- --tries` / `- --spider`) wget consumes `--spider` as the VALUE of
    # `--tries`, spider mode never engages, and every probe DOWNLOADS the
    # response to a file. On the ana-docker instance that left 295,287
    # `healthz.N` files in the container's writable layer, one per probe since
    # April; wget scanning them to pick the next free name is what blew the 10s
    # timeout and made the dashboard card flap. Self-worsening — each probe made
    # the next slower. Watch for `docker exec searxng ls | wc -l` climbing.
    #
    # ⚠ AND KNOW WHAT THIS PROBE DOES NOT TELL YOU: /healthz proves the web app
    # answers. It says nothing about whether any engine returns a result. Seven
    # days of `healthy` sat on top of a search box that found nothing.
