I was thinking only of players but sure DMs probably do some narrative work as DMs even those campaigns that don't have it for players. Not all by any means but some do.
As an example: Fate, and the Fate Point Economy.
In Fate, the player's ability to succeed is strongly influenced by their having Fate Points to spend. The primary way of the player getting Fate Points is by accepting when the GM Compels them, at which point the GM give the player a point, and adds a complication to the scene, thematic to the PC's Aspect being compelled.
Same game, another mechanic:
In Fate, character death is never delivered by strict mechanical results. When a character cannot absorb stress, and is Taken Out of the scene, the responsible party gets to
choose what happens in the narrative. The GM can choose that the character dies. They can also choose that they get captured, left for dead, etc.
Flip side of that, any party in a conflict can choose to Concede, and may thereby choose the nature of their withdrawal from the scene. The villain can always get away, so long as they try before they get Taken Out.
