Consider moving this section before the code example.

| ## How Fallback Works | ||
|
|
||
| - **Primary and Fallback Backends:** You can specify a prioritized list of backends in your `AIGatewayRoute` using `backendRefs`. The first backend is treated as primary, and subsequent backends are considered fallbacks. | ||
| - **Health Checks:** Fallback is triggered based on passive health checks and retry policies, which can be configured using the [`BackendTrafficPolicy`](https://gateway.envoyproxy.io/contributions/design/backend-traffic-policy/) API. |

Worth to mention that the the HttpRouter is sharing the same name with the AIGatewayRoute.
