## DGP canonicalizer for Norm1: ||x||_1 -> sum(x) in log-space
## Since args are already in log-space and all positive, |x_i| = x_i.

.dgp_norm1_canon <- function(expr, args) {
  ## Delegate to sum canonicalizer (matching CVXPY)
  tmp <- SumEntries(args[[1L]], axis = expr@axis, keepdims = expr@keepdims)
  .dgp_sum_canon(tmp, tmp@args)
