"""Platform layer for multi-tenant SaaS capabilities around existing apps.

This package intentionally wraps the legacy applications without requiring
changes inside ``/apps``. It provides request context, tenant resolution,
routing, quotas, secrets, jobs, and structured logging primitives that can be
adopted incrementally by the main Flask entry point.

The directory name is intentionally ``platform/`` to match the requested SaaS
architecture. Because that collides with Python's standard-library
``platform`` module, this package exposes stdlib-compatible attributes at the
top level so existing imports like ``import platform; platform.system()`` keep
working while subpackages such as ``platform.gateway`` remain available.
