- Large Blosc chunks decode about 3x slower than in zarr 2 because `numcodecs.blosc.use_threads` is set to `False` on import
- Several Python threads reading large single-chunk Blosc arrays stop scaling at about 15 reads/s with zarr 3's default codec pipeline (zarr 2: 44, FusedCodecPipeline: 39)
- feat: align Zarr array metadata class names
- fix: tolerate unencodable default_scalar in ShardingCodec.validate
