"""
interactive — additive AI interactive video service.

Parallel to ``studio/``, ``voice_call/``, ``persona_call/``. Lives
entirely in this subpackage; never writes to other modules.

Feature-flagged: ``INTERACTIVE_ENABLED=false`` keeps the whole
surface inert. Enable via ``.env`` once the subsystem is ready to
expose.

Public surface (stable):
    load_config()   → InteractiveConfig
    build_router()  → FastAPI APIRouter (empty router when disabled)

Main mount (additive — single line in ``app/main.py``)::

    from .interactive import build_router as _ix_build, load_config as _ix_load
    _ix_cfg = _ix_load()
    app.include_router(_ix_build(_ix_cfg))

Rollout design: see ``docs/interactive/architecture.md`` (written
alongside later batches). For now, the module exists as scaffolding
so downstream batches can add features without revisiting folder
layout or the mount contract.
