Description: Download, cache, and analyze annual microdata from the
        United States Centers for Disease Control and Prevention
        Behavioral Risk Factor Surveillance System (BRFSS)
        <https://www.cdc.gov/brfss/>. Each requested survey year is
        downloaded once as a compact file hosted on public releases,
        verified against a published checksum, and cached locally;
        queries then run through 'DuckDB' (via the 'duckdb' package),
        so column selection and repeat analyses never re-transfer data.
        Survey-design helpers construct 'srvyr' design objects with
        year-appropriate weights, strata, and primary sampling units,
        including explicit handling of the 2011 weighting methodology
        change and of the codes CDC uses for missing-type answers.
