// instead of 'JSON.parse(JSON.stringify(...))' (see: https://github.com/sindresorhus/eslint-plugin-unicorn/blob/main/docs/rules/prefer-structured-clone.md).
// This may cause warnings when using 'JSON.parse(JSON.stringify(data))'. The reason for using this approach is unclear,
// but it could potentially lead to issues for other developers. Further review is needed to determine if 'structuredClone' should be used instead.
