RackElevationSVG falls back to RACK_ELEVATION_DEFAULT_* config parameters, which raise AttributeError on the target NetBox version. Pass the dimensions explicitly instead. Add a Pillow-based PNG rack renderer (role colors, unit legend, full-depth devices shown dimmed from the other side). It is used for Word when cairosvg is unavailable and replaces a failed SVG in all formats. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
