 # Minimum cargo-nextest for this repository: GHSA-vc25-qg58-w57c is fixed in 0.9.150 and CI
 # installs exactly that version, so an older nextest refuses to run (exit 92 REQUIRED_VERSION_NOT_MET).

+# These measurements require a quiet runner. Their in-process SERIAL mutex only
+# serializes cargo test; nextest gives each test its own process. Reserve all slots
+# so other tests cannot charge their CPU/render-worker time to a frame budget.
