WebVitalsRouteSummary[]

An array of WebVitalsRouteSummary objects summarizing the web vitals for each route.

The function performs the following steps:

1. Groups the data by route and name.
2. Processes each group separately, ensuring the sample size is at least 4.
3. Sorts the metrics within each group by rating and value.
4. Assigns quartiles to the metrics using NTILE(4) logic.
5. Identifies the end of each quartile.
6. Selects only the metrics in quartile 3 where quartile_end is true.
7. Converts the selected metrics into WebVitalsRouteSummary structures.

The resulting summaries include the route, whether the route passes core web vitals, the metrics for LCP, CLS, and INP, and a score.
