/* ============================================================
   Medina Masonry — v5 "coursed"
   Same black / white / signal-red direction as v4, rebuilt so
   the structure reads as masonry: the work section is laid as a
   running bond with mortar joints, and section facts are set as
   a drawing title block rather than stat tiles.
   (v3 "trade-luxe" is archived in themes/.)
