PR description/checklist says all Node.js version references were identified/updated, but there are still hard-coded Node 16 runtime/version references elsewhere (e.g. .github/actions/publish-docker/action.yml uses node-version: 16.x, and template.yml uses Runtime: nodejs16.x; serverless.yml still pins nodejs20.x). Either update those references as part of this PR or adjust the PR scope/description so it’s accurate.
