Expand description

Draw replicate chunks in deterministic draw order without materializing the full n_draws × nobs matrix.

The same RNG is advanced exactly once per observation draw regardless of chunk_draws, so changing the chunk size changes only memory and sink call boundaries, never the generated values. Frontends that write a file or yield an iterator should use this API; collecting the full matrix is an explicit convenience operation implemented below.
