\description{
Synthetic but realistic Brazilian Latossolo Vermelho (Ferralsol per
WRB 2022): deeply weathered, kaolinitic / oxidic, with the canonical
"low-activity clay" signature. Diagnostic outcomes are deterministic
by construction:
\itemize{
  \item \code{\link{ferralic}}: PASSES on horizons Bw1 and Bw2
        (CEC/clay = 8.3 cmol_c/kg clay; ECEC/clay = 3.6 cmol_c/kg
        clay; texture sandy clay / clay; thickness >= 30 cm).
  \item \code{\link{argic}}: FAILS (gradual clay increase, all
        pairwise ratios < 1.2; absolute increment too small for the
        >= 40\% rule).
  \item \code{\link{mollic}}: FAILS (chroma > 3, BS < 50\%, A
        horizon < 20 cm thick).
}
