# Register processors at module initialization. The tiered PDF pipeline selects
# by tier (not priority): Pypdfium2FastProcessor is the ``fast`` tier,
# PyMuPDFProcessor the ``structured`` rollback, and TWO OcrProcessor instances are
# the OCR rungs — ``ocr-incluster`` (the on-demand burst GPU, gateway-only, reached
# via the embedding gateway over the tailnet; e.g. surya) tried before
# ``ocr-upstream`` (paid Mistral). Each is reached only when its own opt-in flag is
# set. OCR gets the lowest priorities so it's never the non-tiered default for PDFs.
