- move common functions to utils.sh: init_paths, read_env_var, write_env_var, is_profile_active, load_env, gen_password, gen_hex, gen_base64, generate_bcrypt_hash - add documentation headers to all installation scripts - replace duplicate code with shared utility calls - consolidate bcrypt hash generation loop in 03_generate_secrets.sh - add DEBIAN_FRONTEND save/restore helpers for whiptail scripts - standardize path initialization across all scripts
