"""Configuration classes for optimization plans.

The [`PlanConfig`][ropt.config.plan.PlanConfig] class, based on
[Pydantic](https://docs.pydantic.dev/), configures optimization workflows
managed by the [`Plan`][ropt.plan.Plan] class. Alongside defining variables for
the plan, `PlanConfig` utilizes
[`PlanStepConfig`][ropt.config.plan.PlanStepConfig] and
[`ResultHandlerConfig`][ropt.config.plan.ResultHandlerConfig] classes to
structure the steps and result handlers that define a complete workflow.
