# Configuration loader for install.sh.
#
# load_install_config <SCRIPT_DIR> [<SOURCE_DIR>]
#   Searches for templates/config/install.conf in either of the supplied
#   directories. On success: sources it, exports TEMPLATES_DIR, returns 0.
#   On failure: applies hard-coded fallback defaults and returns 1.
#
# This function is identical in behaviour to the previous private
# `_load_install_config` inside install.sh; the only change is location +
# accepting the search roots as parameters (so the function is testable
# without globals).
