Cap `money` (one currency, integer minor units), `resource_mutations`, or a workspace-declared unit such as `emails` for the whole environment, optionally narrowed to one action and/or a resource prefix, per `day`, `month` or `total`. Shared by every agent, session and key: none of them is part of a limit's identity. A limit in a declared unit applies to actions that declare an `impact` in that unit. A declared action's resource key is `http:<host><path>`, so `resourcePrefix` can scope a limit to a path prefix. Needs `impact-limits:write`, which no key receives by default.
