"""The pattern applied: a ``random``-style module API over shared state.

One hidden collector is built at import time (cheap: two empty dicts); its
bound methods become the module's public functions. Callers write
``metrics.increment("orders")`` — no instance in sight — while the instance
rides along inside each bound method.
