"""Configuration for the Threads Scraper. Everything can be set with an
environment variable; the defaults work out of the box.

    PORT           port the API listens on (default 8000)
    THREADS_PROXY  proxy URL for every request, e.g. http://user:pass@host:port
                   (default: none — direct). threads.com answered 30
                   back-to-back requests from one IP without a single block,
                   so you very likely don't need this. Set it only if you
                   start seeing failures at high volume.

Everything else below is a plain constant with a working default — edit it
here if you need to.
