#   curl -fsSL https://raw.githubusercontent.com/wlvh/coding-workflow/main/en/scripts/sync.sh | bash
#
# This launcher uses the English template source family under `en/` and installs
# selected templates into canonical target paths such as `AGENTS.md`,
# `TESTING.md`, and `.github/pull_request_template.md`.
