Source code for cadrumo.adapters.inbound.borrador._parsers.pdfplumber_backend

"""Pdfplumber-backed page text extraction for Modelo 100 PDFs.

Implements the single
``adapters.inbound.borrador._parsers._pdfplumber_backend.extract_pages_text``
primitive that the borrador extractors consume. The function isolates the
pdfplumber dependency so other backends (e.g. pdfminer, OCR) can be swapped in
without touching extractor code.

The backend delegates to
:func:`~adapters.inbound.pdf.page_text_extraction.extract_pages_text_from_path` and
wraps failures in :class:`~adapters.inbound.borrador.errors.BorradorParseError`
so callers stay inside the borrador parse-error family.
