"""Guard for the aggregate ``all`` extras in pyproject.toml.

Review of #1508 caught ``parse-pdf`` missing from every ``all`` bundle:
``semantica[all]`` installed the package without pdfplumber, so the default
PDFParser raised ProcessingError on first use. tomllib is stdlib only from
Python 3.11, so the bundle block is parsed textually — the repo still
supports 3.9/3.10.
