WillTools 2026-09-09 -- clean snapshot of the development repo for review

History-free snapshot of the private development repository at cbe45c5
(2026-09-09). Code, docs and public catalogue only; no plant or job
knowledge layers, no client or job names (tools/scrub.py clean). The
intro deck is left out of this snapshot because its slide images could
not be checked for job drawings.

+"""Two constraints, not one, and they are not the same inserts.
+
+A panel erected on its END carries its anchors in that end: they cannot move
+along the piece, and where they sit across it is still a choice.
+
+A panel erected on its long EDGE carries them along that edge: they may slide
+freely down the length, and they may not come off the edge.
+
+Collapsing both into one "pinned" flag gets one of the two wrong, and the
+wrong one is a recommendation to put an anchor where the piece has no edge.
