WSGI entry point — Apache mod_wsgi deployment.

Usage:
  Apache config:
    WSGIDaemonProcess financials python-home=/var/www/html/financials/.venv
    WSGIScriptAlias / /var/www/html/financials/wsgi.py

  Local development (preferred):
    export FLASK_APP=wsgi.py FLASK_DEBUG=1
    export DATABASE_URL=sqlite:///financials.db
    flask run

  Behind a reverse proxy at a sub-path (e.g. Apache proxying /financials → :5000):
    export URL_PREFIX=/financials
    flask run
"""

# When served behind a reverse proxy at a sub-path, set SCRIPT_NAME so
# Flask's url_for() generates correct URLs including the prefix.
# Apache already strips the prefix from PATH_INFO before forwarding —
# this middleware only sets SCRIPT_NAME so link generation works.
