+These five outputs supersede the prior published PNGs for the same targets.
+Each was generated with the original non-crisp JPG **and** the retained
+bounded crop as imagegen inputs. The final PNGs were inspected at native
+resolution and at a simulated 608px lesson width. C2PA metadata was checked
+in each published output; the URN is recorded below.
