Creates a pacing rule. An `hours` rule holds mail outside the weekly windows you declare, evaluated in the rule's own timezone. A `limit` rule caps sends per rolling window against a scope — the rule as a whole, or per sender address, sending domain, recipient, or recipient domain. An empty `match` array applies the rule to every send. `space_id` makes the rule read one space's mail alone; workspace rules apply to every space and stack on top.
