📄 Description

Marked as draft, as there are few tess validation warnings left to fix, yet so far the implementation is reliable enough. For the next steps it would be nice to:

minimize latency on new PL creation (there is a room for improvement in serialization sequence)
async schedule for IO
single container (miniz) + zlib compression for blobs
