+-   **Automatic POCO Generation:** Mirrors your `appsettings.json` structure into clean, ready-to-use C# records.
 -   **Strongly-Typed Access:** No more `_configuration["Section:Key"]`. Access settings with `options.Value.Section.Key`.
 -   **Seamless DI Integration:** Automatically generates extension methods to register your configuration with Dependency Injection using the `IOptions` pattern.
 -   **Zero Runtime Overhead:** All code generation happens at compile time, adding no performance cost to your application.
