# ezdxf and shapely both look transitive through build123d, and both are kept
# DIRECT on purpose: cadgen imports each one itself, so each is its own
# dependency regardless of who else happens to pull it in.
#
# ezdxf stopped being a WRITING dependency when @dxf moved to build123d geometry
# (cadgen._internal.dxf_emit) -- the engine writes through build123d's ExportDXF
# and no author-facing contract mentions ezdxf. It remains a READING one, which
# is not going away: cadgen.drawing_payload flattens a .dxf to draw it (for the
# Viewer's pane and for `cadgen dxf snapshot` alike), and cadgen.drawing_checks
# parses one to validate it post-hoc. A DXF reader needs a DXF parser. Dropping the declaration would leave those two modules resting on
# build123d's own dependency list, and they would fail at a user's runtime, not
# at install, the day that list changes.
#
# shapely is likewise narrower than it was -- flatten's unions and offsets are
# OCC operations now, with shapely only the fallback for the degenerate unions
# OCC refuses -- but a fallback that is not installed is not a fallback.

  # Bounded above on purpose. cadgen does not merely CALL build123d, it
  # reaches into it: the determinism shim shadows `set` in three topology
  # modules and replaces `Vertex.__hash__`, and the lazy store replaces
  # `Compound.__init__` and reads its arguments BY POSITION. A minor release
  # is free to reorder that signature or rename those choke points, and the
  # failure mode is silent: a patch that no longer matches simply stops
  # applying. Raise the ceiling deliberately, after re-running the suite
  # against the new minor.

  # requirement (`cadgen[snapshot]`) would be a second installation. Pinned exactly: each

  # browser whenever it moved. The browser itself is fetched on the first snapshot
