Reviewer's Guide by Sourcery

The PR refactors the HTML cleaning process in the pages view by introducing a centralized bleach Cleaner configuration. The changes move the cleaning configuration from being defined inline to a module-level constant, while also updating the implementation to use new safelinks functionality.
