Chrome flags for testing:
| `chrome://flags/#top-level-third-party-cookie-deprecation-trial` | disable to see how the site would work without the trial
| `chrome://flags/#tracking-protection-3pcd` | enrolls the browser into third-party cookie blocking (normally only 1% of browsers at this time)
| `chrome://flags/#tpcd-metadata-grants` | disable to see how the site would work without metadata grants (which are basically identical to the deprecation trial, but are enabled by Google based on having filed a report like [[https://issuetracker.google.com/issues/329250103|#329250103]] rather than controlled by the site itself, and will end much sooner)
