Changes in version 0.1.0 (2026-05-29)                  

Initial CRAN release.

  - Covariance-aware derived-estimate helpers: acs_sum(), acs_diff(),
    acs_ratio(), acs_prop(), acs_product(), acs_linear(). With no
    covariance supplied, results match the zero-covariance ACS
    approximation formulas used by tidycensus.
  - Grouped paired estimate/MOE aggregation via acs_aggregate(), with
    cov_strategy = "zero" (default) and cov_strategy = "constant" for
    sensitivity analysis.
  - Simulation helpers acs_simulate() and acs_simulate_fn() for derived
    quantities from estimate/MOE pairs.
  - MOE/SE/CI conversion utilities: moe_to_se(), se_to_moe(), moe_ci().
  - Reliability diagnostics: acs_cv() and acs_reliability().
