abstract: 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.
