Switching from pnpm install --ignore-scripts to a normal pnpm install will now execute lifecycle scripts during CI (notably the root postinstall: husky from package.json). If the goal is primarily to run the fixture preparation, consider disabling husky in CI (e.g., set HUSKY=0 in job env) to avoid unnecessary hook setup and potential CI flakiness/time cost while still allowing prepare to run.
