    ## Common Examples

    ### Basic Usage

    Interactive prompt with radio options:

    ```tsx theme={null}
    import { SystemMessage } from "@servicetitan/anvil2-ext-atlas";

    function SystemMessageExample() {
      const [selected, setSelected] = useState("");

      return (
        <SystemMessage
          message="How would you like to proceed?"
          radioOptions={[
            { value: "continue", label: "Continue", description: "Proceed with current settings" },
            { value: "modify", label: "Modify", description: "Change the settings first" },
          ]}
          selectedValue={selected}
          onRadioChange={setSelected}
          buttonText="Confirm"
          onSubmit={() => handleSubmit(selected)}
        />
      );
    }
    ```

    ### With Disabled Submit

    Disable submit until selection is made:

    ```tsx theme={null}
    import { SystemMessage } from "@servicetitan/anvil2-ext-atlas";

    function SystemMessageDisabled() {
      const [selected, setSelected] = useState("");

      return (
        <SystemMessage
          message="Choose an option to continue"
          radioOptions={options}
          selectedValue={selected}
          onRadioChange={setSelected}
          buttonText="Continue"
          onSubmit={() => handleSubmit(selected)}
          buttonDisabled={!selected}
        />
      );
    }
    ```
  </Tab>
