function keyboardInset(view: {
  readonly innerHeight: number
  readonly visualViewport: {
    readonly height: number
    readonly offsetTop: number
  } | null
}): number

The part of the layout viewport's height below the visual viewport: what the on-screen keyboard covers. Rounded down, since a fraction of a pixel of zoom is no keyboard.
