# update.sh — pull tooling updates into an existing docs-scaffold install.
#
# Only replaces tooling files (doc-check.ts, workflows, PR template).
# Leaves your AGENTS.md, CLAUDE.md, docs/agent/*.md content alone.
#
# Usage:
#   From your project root:
#   curl -fsSL https://raw.githubusercontent.com/lanceretter/lance-stack-template/main/docs-scaffold/update.sh | bash
