Follow-up on the Perfetto trick: each bar in the resulting timeline is one GitHub Actions job, and clicking it expands the individual steps within — handy for finding CI bottlenecks.
One caveat: asking the agent for a Google Chrome-compatible trace file broke the nesting, so stick with the .pftrace format for Perfetto.
