script generation

Tired of drift and risky manual edits? This guide shows how to auto-generate environment-specific deployment scripts with pure Bash: keep config in one JSON file, use a Bash template, and render with a tiny jq+envsubst script to produce dist/deploy-*.sh for dev/staging/prod. Gain consistency, auditability, and safer rollouts, plus extras like a Makefile, validation, dry-run, versioning, and easy CI integration.
