# Path resolution. Split out of bootstrap.source.sh (task jn0) so the install /
# source-root / default-directory discovery and the rc-file/template-dir
# defaulting live apart from startup wiring and logging. These helpers resolve
# where the packaged config, templates and assets live (both when installed and
# when running from a source checkout) and initialise a fresh shuriken.conf.
# All library modules are sourced before any code runs, so definition order does
# not affect availability (e.g. init_config calls log_info from
# logging.source.sh).
