Looks solid. Left a question on the fallback examples (same static-route case as #23424) and a note on streamed e2e attribute assertions.


```ts
// With span streaming, span names have to be low cardinality, so we can't fall back to the URL.
name: parameterizedRoute ?? (hasSpanStreamingEnabled(client) ? NAVIGATION_SPAN_NAME_FALLBACK : pathname),

I guess same question as on #23424, we can align on that before changing this.


The scope is only a valid fallback for standalone spans, which are sent without their segment span. `packages/browser-utils/src/web-vitals/spans.ts` is the worked example.

Could we note that toMatchObject against a plain string / url.pathname will fail for streamed e2e attributes here so the next op doesn’t copy #23424’s assertions? 👀
