"""Bounds tests for ZernioConfigRequest + PublishRequest.scheduled_for.

The Zernio config endpoint and publish schedule accept user-supplied strings
that land in data/config.json and the scheduler. These pin the size/shape
guards: unbounded api_key, oversized/odd accounts maps, and a giant
scheduled_for string are all rejected at the Pydantic boundary; normal
payloads pass.
