"""The app-owned batch_align profile: this deployment's alignment config.

The SDK ships the BatchAlignProfile schema + params bounds; the VALUES a
deployment runs are consumer config and live here. Derive per-request copies
via ``SPACE.model_copy(deep=True)`` — never mutate the module instance.
Import-light: pulls pydantic params modules only, no torch.
