parseIfcUrl, buildIfcUrl, toRawUrl extracted from viewer.html into viewer-url.js so they can be imported and tested independently. viewer.html imports from the module. 32 Node test-runner tests in tests/test_viewer_url.mjs cover all three functions across GitHub, GitLab, Forgejo/Gitea, SSH user@ prefix, and round-trip cases. Caught a bug: + (selector union operator) was being URL-encoded as %2B in buildIfcUrl; fixed by adding .replace(/%2B/g, "+") alongside the existing comma fix, in both viewer-url.js and syncCameraUrl.
