# Vercel "Ignored Build Step" (see website/vercel.json).
# Exit 0 = skip the build, exit 1 = build. Vercel's working directory is website/.
# Exit 0 = skip the build, exit 1 = build. Any other exit code makes Vercel
# fail the deployment, so every error path below must end in exit 1 (build).
# Vercel's working directory is website/.
# - Production always builds.
# - A preview whose commit message contains "[vercel skip]" is skipped (deploy budget).
# - Otherwise build only when website/, docs/ or CHANGELOG.md changed.
# - If the previous deployed commit is unavailable (e.g. the branch was
# force-pushed, or it is outside Vercel's shallow clone), build.
