"""
Internationalization (i18n) module for MemoryBear Enterprise.

This module provides complete i18n support for the backend API including:
- Translation loading from multiple directories (community + enterprise)
- Translation service with caching and fallback
- Language detection middleware
- Dependency injection for FastAPI
- Convenience functions for easy usage

Usage:
    from app.i18n import t, t_enum

    # Simple translation
    message = t("common.success.created")

    # Parameterized translation
    error = t("common.validation.required", field="名称")

    # Enum translation
    role_display = t_enum("workspace_role", "manager")
