 Render evidence shows the exact revision and abbreviated template, input, and
 output hashes. A consumer such as Campaign can submit many frozen recipients;
 the UI sample intentionally validates one representative item.

+Rendering is also limited to 15 seconds elapsed time, 10 CPU seconds, 512 MiB
+process memory, 32 MiB serialized input and 8 MiB serialized result transport;
+the final output remains limited to 5 MiB and 5,000 items. Deeply nested data
+or more than 1,000,000 transported value nodes is rejected. A limit error creates
+no partial output or render evidence: reduce the selected input or template
+complexity and retry. If processing capacity is busy, retry later. Unavailable
+worker controls or a worker failure require operator investigation. Existing
+successful output with the same idempotency key is reused without rendering
+again, provided its input and authorization still match.
