🌟 About the Project & Pipeline Demarcation

This project encompasses the complete historical processing, multimodal AI transcription (Mistral OCR), gapless canonical alignment against the Aṣṭādhyāyī Sūtrapāṭha, and the generation of standardized digital edition artifacts for Otto von Böhtlingk's landmark 1887 Pāṇini edition based on scans from the Heidelberg University Library.

ℹ️ Relation to the AlexandriaSandwich Pipeline:
All generic steps of image processing, IIIF caching, multimodal AI OCR (mistral-ocr-latest), Content-Aware Margin Masking (#f0e8d6), and 1:1 sandwich PDF assembly are powered by the core book digitization pipeline AlexandriaSandwich.
