// Package platform is the shared seam library for the e-commerce platform.
//
// It holds the small, stable interfaces and helpers that every module may
// import WITHOUT importing another module's internals: env/config loading,
// the AMQP and HTTP client factories, OpenTelemetry setup, graceful shutdown,
// and the cross-module event vocabulary.
//
// Dependency rule: packages under platform/ import only third-party libraries
// and other platform/ packages — never an application module. Application
// modules depend downward onto platform. This is what keeps it a stable seam.
//
// See docs/platform-uniforming-plan.md for the layout and the migration order.
