# Active Support 7.2 calls `JSON.generate(..., quirks_mode: true)` and
# `JSON.parse(json, quirks_mode: true)`. The json gem removed `quirks_mode` in
# 3.0, so an unpinned json resolves to 3.x and every `to_json` in the app raises
# ArgumentError - webhook payloads and JSON API responses included. The Gemfile
# pins json to < 3 because of this; these examples fail loudly if that pin is
# removed before we are on a Rails version that no longer passes the option.
