Explanation: Sylius RBAC Plugin

This plugin adds a permissions and roles system to Sylius, an open-source e-commerce platform. In plain terms, it lets you create different admin user accounts with different levels of access. One admin might only manage customer data, while another can also change product catalogs or system settings. This prevents anyone with an admin login from accidentally—or intentionally—making changes they shouldn't.

The way it works is straightforward: you define roles (like "Customer Manager" or "Catalog Editor"), and each role has a set of permissions tied to specific parts of the admin interface. When you assign a role to an admin user, they can only access and modify the sections their role permits. The plugin comes pre-configured with Sylius's main sections—catalog, configuration, customers, marketing, and sales—but you can also create your own custom sections if you add features the plugin doesn't know about yet.

You'd use this if you're running a Sylius store with a team. Instead of giving everyone the same admin password, you can create role-specific accounts that limit damage from compromised credentials or mistakes. For example, an intern managing customer emails doesn't need access to financial settings, so you'd give them a "Customer Support" role with only customer-facing permissions.

One important detail: when you give someone write access to something, they automatically get read access too. And write permission includes the ability to update and delete records, not just create new ones. The plugin uses a trait-based architecture to extend the existing AdminUser entity, so it integrates cleanly with your Sylius installation without replacing core code.
