# app/config/menu_registry.py
"""
Menu registry for Admin and Vendor frontends.

This module defines the complete menu structure for both frontends.
Menu items are identified by unique IDs that are used for:
- Storing visibility configuration in AdminMenuConfig
- Checking access in require_menu_access() dependency
- Rendering the sidebar dynamically

The registry is the single source of truth for menu structure.
Database only stores visibility overrides (is_visible=False).
