Conversation
New spec page: the 50 ms long-task budget behind INP — slice and yield with scheduler.yield() (Chrome/Edge 129, Firefox 142, Safari not yet; setTimeout fallback), worker offload beyond ~250 ms, and LoAF field attribution. Reciprocal relatedSlug on core-web-vitals, changelog entry, OG image, skill digest. From the Modern Web Guidance review.

…t starve input Review finding: my wording had the mechanism backwards. A setTimeout yield does let the browser process input between slices; the real cost is that the continuation queues behind other tasks (and nested timeouts clamp). Rewritten accordingly.

New page from the Modern Web Guidance review: long tasks (performance, recommended).
The remediation discipline that core-web-vitals states only as a metric: the 50 ms task budget, the run/slice/offload heuristic,
scheduler.yield()with its current support (Chrome/Edge 129, Firefox 142, Safari not shipped — fallback required),scheduler.postTask()priorities, and Long Animation Frames attribution in RUM.Includes: changelog entry (dated 2026-11-11, re-date if it sits), reciprocal relatedSlug on core-web-vitals, OG image,
sign:skilldigest.Environment note, same as #306: only the new page's own OG image is committed; shared count images need a maintainer
