"""PyInstaller hook for pypdfium2.

``pypdfium2`` ships the native PDFium shared library as a data file
inside its package directory (``pdfium``-prefixed ``.dll`` on
Windows, ``.so`` on Linux, ``.dylib`` on macOS). PyInstaller's
default discovery picks up Python ``.py``/``.pyc`` but can miss
the binary if the package is wheel-installed and the shared lib
isn't on the ``__init__``'s module-level path it scans.

This hook is belt-and-braces — the main spec already calls
``collect_data_files("pypdfium2")`` and ``collect_submodules``,
but PyInstaller's hook-discovery-by-name is the documented
escape hatch for native-bundled libraries. Without this, the
visual picker (which renders PDF pages via
``pypdfium2.PdfDocument(...).render(...)``) silently fails on
installed builds with a ``FileNotFoundError`` for the PDFium
shared library.
