strip_svg_hyperlinks() removed every href, including on <image> elements that reference device-type photos, leaving devices with images blank in the exported file. Non-anchor hrefs (currently only <image>) are now resolved through an optional image_loader callback and embedded as base64 data URIs instead of being stripped; anchor unwrapping is unchanged. RackElevationOfflineSVGView wires this up to NetBox's MEDIA storage. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
