…lip pin gets a bounded settle window The fps harness asserted wall-clock frame pacing (p95, zero >33ms outliers) — a benchmark, not a correctness pin; on shared GH runners without GPU it fails deterministically. Moved to perf.bench as FPS-churn-presence, mirroring FPS-churn so the report isolates the presence frame-pacing tax. The reverse-flip pin gave the settle chain (scheduled render -> observer -> coalesced flush -> host render) exactly one rAF — an ordering neither the spec nor React guarantees; headless webkit reliably fires rAF first. settlesWithin polls up to 5 frames: liveness stays pinned, the unguaranteed single-frame budget goes.
