# Vehicle Catalog CSV Bulk Import Wrapper
#
# Copies CSV file into mvp-backend container and executes bulk import script.
# Handles large CSV files (250k+ rows) that fail in web import.
#
# Usage:
#   ./import_catalog.sh <path_to_csv_file>
#
# Example:
#   ./import_catalog.sh data/vehicle-etl/import/vehicle-catalog-master.csv
#
# Requirements:
#   - mvp-backend container must be running
#   - CSV file must have headers: year, make, model, trim
#   - Optional headers: engine_name, transmission_type
#
