Odd Rule Lab original developer sample. Unpacked Manifest V3 extension. No requested host permissions, analytics, data storage or network calls in its code.

Load the folder as an unpacked extension only in a separate testing profile using official browser developer instructions. The toolbar action opens popup.html. Enter a full UTC timestamp ending Z and an IANA zone.

Developer prototype only: not a Chrome Web Store listing, signed package, auto-update channel or compatibility claim across all browsers. Time-zone data comes from the browser and can be outdated. No meetings are booked.
