kind

readonly kind: "flex"

min?

readonly optional min?: number

Optional floor in whole cells: this item is never solved below min, even as the container shrinks. When no item on the track carries a min, the solver runs its plain apportionment untouched (the no-min fast path), so the field is free for every existing caller. When the floors are collectively unsatisfiable — their sum exceeds the available space — every item squeezes proportionally rather than overflow the track.

weight

readonly weight: number
