Re: [csswg-drafts] [css-grid] Decide on a name for `item-slack` (#10884)

What about `flow-margin`?

To use @jensimmons's car metaphor - imagine every car has an invisible, adjustable rear bumper extension - the **_flow-margin_**.

Low flow-margin: The bumpers are tight. If Car 4 is even an inch shorter than Car 1, the driver of Car 6 sees that "gap" and swerves into the right lane to get ahead.

High flow-margin: The bumpers are long. Even if Car 4 is shorter, its flow-margin covers the difference. Car 6 stays put because, according to the "margin," there’s no meaningful room to move forward.
