Clarify that the 2 MB payload limit is a per-request maximum, not a sustained-throughput target, and that Temporal reserves the right to rate limit high-volume large-payload traffic. Point readers to External Storage for workloads that regularly produce large payloads. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Adds a note to the Transaction Payload size limit section of the Temporal Cloud limits page clarifying that the 2 MB payload limit is a per-request maximum, not a sustained-throughput target, and that Temporal reserves the right to rate limit high-volume large-payload traffic to protect the service. Points readers to External Storage for workloads that regularly produce large payloads.
Why
Customers have read the documented 2 MB payload limit as a guarantee that sustained, high-volume 2 MB payloads will be served at scale. In practice, sustained large-payload traffic can degrade Namespace performance even though any single request is within limits.
