"""
Human+ Core AI Layer
====================
Semua logika AI, RAG, PDF processing, chart, dan report generation.

Cara pakai:
    from core.ai_client import call_gemini, get_client
    from core.rag_engine import get_vector_store, retrieve_context
    from core.pdf_processor import extract_biomarkers
    from core.protocol_generator import generate_protocol
    from core.chart_builder import build_gauge_chart, GAUGE_PRESETS
    from core.report_generator import generate_pdf_report

Modules:
    ai_client          — Gemini client singleton + call_gemini() wrapper
    rag_engine         — FAISS vector store loader + MMR retriever
    pdf_processor      — PDF → structured biomarker list via Gemini
    protocol_generator — Biomarker + RAG context → protocol dict via Gemini
    chart_builder      — Plotly figure builders (gauge, bar, donut)
    report_generator   — Branded PDF report via reportlab
