"""PocoFlow — lightweight LLM workflow orchestration.

A hardened evolution of PocketFlow's core idea:
  every node is a nano-ETL unit  →  prep | exec | post
  nodes connect via named action edges  →  no routing ambiguity
  a shared Store is the single source of truth  →  typed, observable, checkpointable

Built with love by Claude & digital-duck.
