    # This is the Regex pattern for variables to ignore. Because ESLint seems to
    # have trouble recognizing that we DO use the React elements we build with
    # JSX, we end up having to explicitly whitelist every single React element
    # we use.
    # When using multi-line strings in YAML as we're doing it, the line breaks
    # turn into spaces. To combat this, we put a Regex or operator (|) at the
    # beginning and ending of every line, so the Regex ends up basically saying
    # "or space" a whole bunch, which is fine.
