Commands used to keep rendering resources directly in the variant: image frames, external content and video sources, filters, SVG paint styles, and nested display lists. That makes the command stream own its dependencies and prevents it from becoming a POD-like byte buffer. Add DisplayListResourceStorage and replace those command fields with stable resource IDs. The storage deduplicates resources by their existing IDs and can copy only the resources referenced by a captured command sequence, giving the future IPC boundary a clear list of resources that must be communicated to the rasterization process.
