- ifcurl/bcf.py: build_bcf() builds BCF 2.1 zips with perspective/
orthographic camera, clipping planes, component selection, and
isolate visibility mode
- ifcurl/service.py: /bcf POST endpoint parses ifc:// URL, resolves
selector → GUIDs when present, delegates to build_bcf()
- viewer.html: BCF toolbar button + collapsible title/comment form;
client-side zip generation via JSZip (esm.sh CDN) so the browser
does not need service access
- tests/test_bcf.py: 21 tests covering build_bcf() unit behaviour and
the /bcf endpoint including SSRF rejection and selector resolution
