"""Serializers for the ``configs`` API.

Reads expose ``key``, the (possibly masked) ``value``, and the definition
metadata the UI needs to render a form. Writes carry only ``value``; coercion and
validation happen in :class:`~infrasynth.configs.services.ConfigService` so there
is a single source of truth.
