Setiap file adalah satu step dalam 3-step user flow.
Dipanggil dari streamlit_app.py berdasarkan st.session_state.step.

Flow:
    step 1  →  pages/upload.py    — Upload PDF lab
    step 2  →  pages/analysis.py  — AI analysis + biomarker dashboard
    step 3  →  pages/protocol.py  — Protocol generation + PDF download

Cara pakai (dari streamlit_app.py):
    from pages.upload   import render_upload_page
    from pages.analysis import render_analysis_page
    from pages.protocol import render_protocol_page

Session state yang digunakan antar page:
    st.session_state.step                 — int: current step (1|2|3)
    st.session_state.uploaded_pdf_bytes   — bytes | None
    st.session_state.pdf_filename         — str | None
    st.session_state.extracted_biomarkers — list[dict] | None
    st.session_state.generated_protocol   — dict | None
