  JUE replaces mismatched Halvorsen-Palmquist 1980 AER metadata; Irwin 2002
  Land Economics open-space paper replaces Irwin-Bockstael; Goodman-Thibodeau
  1995 heteroskedasticity paper replaces 1998 segmentation mismatch).
- Des Rosiers et al. (2002) landscaping premium range verified (4-12%) and
  stated precisely in the discussion.
- ~700-character description truncation confirmed empirically in the raw DB
  (pile-up at 701-703, mid-word cuts before GST/QST boilerplate).
