All code and API mappings must be cross-platform; do not use macOS-only APIs unless equivalent Linux and Windows implementations are provided.
Gitea Actions workflows must target only `ubuntu-latest`; do not add macOS or Windows Gitea jobs.
Crates named `libremetaverse-*` are restricted to compatibility mappings of the C# LibreMetaverse libraries. New MetaCrate-native functionality must use a `metacrate-*` crate name; the reusable wgpu renderer is `metacrate-rendering-wgpu`.
