Draw cutoff anchors as a measured position guide

guide_cutoff() draws one truthful marker rail and, when requested, one measured label lane per helper call. Two-sided labels dodge along that lane while their leaders remain tied to the truthful cutoff anchors. The guide receives already-computed cutoff values; it never inspects the distribution or recomputes a statistic.

Usage

guide_cutoff(
  value,
  label = NULL,
  side = NULL,
  call_id = 1L,
  colour = ggplot2::waiver(),
  shape = 24,
  size = 4,
  linewidth = 0.5,
  title = NULL,
  theme = NULL,
  order = 0,
  position = ggplot2::waiver()
)
