The editor that follows you across devices

Monday morning, you open your laptop in a coffee shop. The bookmark loads VS Code in Firefox. You write for an hour.

Tuesday, you're at a client's office on a borrowed Chromebook. Same bookmark. Same VS Code, same files, same open tabs, cursor in the same place.

Wednesday, you're on a flight, on an iPad with a keyboard case. Safari, same URL. The instance you left running on Tuesday picks up where you stopped.

Thursday, you check on something from your phone in line at the airport. The editor renders. You read the function you wrote yesterday.

There's no Dropbox sync, no git push origin work-in-progress, no "let me grab my laptop." The state isn't on a device. The state is on the container, and every device is a viewer of the URL.
