Convert	PDF → MD	Skips existing
Chunk	Headers → Recursive	Preserves H1/H2
Embed	Global cache	0.1ms/query
Index	Pinecone upsert	Only new chunks

🌍 Domain Agnostic

curl /full-pipeline -F "files=@legal.pdf"     → Legal Q&A
curl /full-pipeline -F "files=@medical.pdf"   → Patient queries
curl /full-pipeline -F "files=@tech.pdf"      → Support tickets
curl /full-pipeline -F "files=@finance.pdf"   → Analysis

No code changes! Just upload → query.
