Save mesh: the VTK viewer's Save button POSTed to /geometrypack/save_preview,
a route that was never ported into GeometryPack (inherited caller from
comfy-3d-viewers; only /gpack/getpath existed). ComfyUI's GET catch-all
matched the path, hence 405 instead of 404. Added POST /gpack/save_preview in
__init__.py next to getpath: basename()-sanitized lookup of the temp preview
export in ComfyUI output/ (tempdir fallback), copied to output/saved_<name>;
returns {success, saved_filename}. Viewer fetch updated to the new path.
Multi cols/rows: entering dims whose product was smaller than the mesh count
(e.g. 1x1 for 2 meshes) overflowed viewports into IMPLICIT CSS grid rows
(auto height), so the rendered layout stopped matching the inputs. Now the
edited field is authoritative and the other dimension auto-raises to fit
(ceil(n/edited)); both inputs are updated to show the grid actually in
effect. Oversized grids (empty cells) remain allowed.
