Prerender Sizing
Pick or adjust the prerender server's pool envelope (`PRERENDER_PAGE_POOL_MIN` / `_MAX` / `_HIGH_PRIORITY_MAX` / `_HIGH_PRIORITY_THRESHOLD` / `_IDLE_CONTRACTION_MS` / `_SHARED_CONTEXT_CAP`) and ECS task CPU/memory using observed telemetry, not round-number intuition. Use this skill whenever an operator asks "are we sized right?", wants to change the envelope after a workload shift, considers a new ECS task size, or hits memory pressure / OOM on the prerender service. Layers on top of the `aws-access` skill for the underlying CloudWatch + DB plumbing; that skill is a prerequisite.
