For many small files (< block size), enable block dictionary:

pureonyxzip create archive.poz \
  --train-dictionary sample_set/*.js \
  --dict-id 0xCAFEBABE \
  --apply-dict-to-blocks

This trains a Zstd dictionary on representative samples, then applies it to every block — improving ratio on tiny files by ~30%. pureonyxzip best
