Problem

You're auditing a batch of JSON event payloads whose objects and arrays nest arbitrarily deep, and you need a tally of the integers buried inside them. Count how many times each genuine integer value appears anywhere across every payload, returning a map from the integer's string form to its total, where floats and booleans never count, not even a whole-looking `100.0` or a bare `true`.

Summary

JSON strings are hiding numeric secrets. Dig them out.
