# A ConfigMap's data values must be **strings**, and this file cannot enforce
# that: kustomize re-serialises before Flux substitutes, stripping both quotes
# and an `!!str` tag, so `${VAR}` is always bare by the time a value lands in it.
# A value that then looks like a number or a boolean parses as one and the apply
# fails on the type.
#
# So any value substituted here that is not obviously text must carry its own
# quotes in the substitution map:
#
#     EXECUTIONS_MAX_AGE_HOURS: '"336"'
#     BLOCK_ENV_ACCESS: '"false"'
#
# Nothing here is sensitive. The two values that are — the database password and
# the credential encryption key — arrive through n8n-secrets.
