## Adding New Pages

To add a new page, create a new directory in src/app with a page.tsx file, following the Next.js App Router conventions.

## Observability Configuration

The frontend exports Web Vitals to an OpenTelemetry collector. Configure the target collector via environment variables before running the app:

| Variable | Description |
| --- | --- |
| `OTEL_COLLECTOR_HOST` | Hostname or IP address of the OTLP collector. |
| `OTEL_COLLECTOR_PORT` | (Optional) Port where the collector listens (defaults to `4318` when omitted). |
| `OTEL_COLLECTOR_PROTOCOL` | (Optional) Protocol to use (`http` by default). |
| `OTEL_COLLECTOR_PATH` | (Optional) OTLP path, defaults to `/v1/traces`. |
| `OTEL_COLLECTOR_URL` / `OTEL_EXPORTER_OTLP_ENDPOINT` | (Optional) Full collector URL that overrides the host/port variables. |

You can also set `OTEL_SERVICE_NAME` to override the service name reported by the exporter.
