-"""Generic face-quad resize gizmos for any axis-aligned local box.
-
-This module contains the box-agnostic core of the interactive
-face-resize gizmos: two Gizmo classes (a near-invisible click target
-welded to each face, and a thin colored edge outline), a per-redraw
-orchestrator that places six of each on a box, and the pure one-sided
-resize arithmetic. None of it knows about IFC, clip boxes, or
-``BIMSceneClipBoxProperties`` — a future camera-view-box adapter can
-reuse the same classes and helpers.
-
-Consumer contract — the adapter group must:
-
-1. Create six ``BIM_GT_box_face_quad`` and six ``BIM_GT_box_face_outline``
-   instances at ``setup()`` time, in :data:`FACE_ROUTES` order, and bind
-   each quad's ``move_get_cb`` / ``move_set_cb`` to closures that read
-   and mutate the box's host (e.g. an Empty's ``location`` / ``scale``).
-2. Call :func:`apply_face_quad_layout` from ``refresh()`` /
-   ``draw_prepare()`` with the box's local-frame ``bmin`` / ``bmax``,
-   the host's ``matrix_world``, the OBB rotation as a 4x4
-   (``Matrix.Identity(4)`` when the rotation rides in ``matrix_world``),
-   and the current ``region`` / ``rv3d``.
-3. Implement ``_lock_for(active_gz)`` / ``_unlock_all()`` on the group
-   for drag mutual exclusion; the quad's ``invoke`` / ``exit`` call them.
-
-The resize arithmetic in :func:`compute_face_resize` is pure: feed it
-the modal scalar plus drag-start snapshots and it returns the host's
-new scale-on-axis and new origin location.
