RE.11 Unreal inside Studio with no install: ship a packaged CadCraft renderer built with Unreal

Studio could draw with Unreal without the person installing it, but the Unreal Editor itself cannot be redistributed as far as we know (tens of GB, Epic's EULA). What could ship is our own packaged program built with Unreal that loads our scene and draws it, under Epic's royalty and attribution terms. Problems: gigabytes added to the installer; separate Windows, Mac and Linux builds; a packaged build may not read USD at runtime like the Editor, so it would load glTF and lose fidelity; native code people download, against KICKOFF rule 44 (content first). Desktop only: it does nothing for the browser edition.

Not promising soon (owner 2026-11-06). Licensing points are from memory, not checked against Epic's terms. Full write-up: docs/spikes/RE-unreal-hosted.md.
