/**
 * The limits are declared twice on purpose: `@n8n/api-types` owns the copy the
 * request schema and the frontend read, while `@n8n/instance-ai/parsers` keeps a
 * dependency-free copy so that entry point stays consumable from lightweight test
 * environments. This is the guard that stops the two from drifting — drift would
 * mean the schema accepts a payload the validator rejects, or vice versa.
