\title{Test for an abrupt textural change between adjacent horizons}
\usage{
test_abrupt_textural_change(h, min_ratio = 2, require_abrupt_boundary = TRUE)
}
\arguments{
\item{h}{Numeric threshold or option (see Details).}

\description{
WRB 2022 planic criterion: clay content of the underlying horizon is
at least double that of the overlying horizon, with the transition
occurring within 7.5 cm vertical distance. v0.3 implements the
clay-doubling test plus an optional \code{boundary_distinctness}
check (must be \code{"abrupt"} or \code{"very abrupt"} on the upper
horizon).
