# sync-env.sh — Ensure .env has every key from .env.example
#
# Reads .env.example as the source of truth. For any key that is
# missing in the local .env, appends the .env.example value (or
# a placeholder) under the same section comment. Existing keys in
# .env are preserved (never overwritten) so secrets stay intact.
#
# Usage:
# ./scripts/sync-env.sh # sync into .env
# ./scripts/sync-env.sh --check # report missing keys only
# ./scripts/sync-env.sh --target .env.production
