Steps to reproduce
- Run

http://127.0.0.1:4096/on a browser, start a new session. I ssh port forward to my Windows 11 Home PC and access it there. - Now
http://127.0.0.1:4096/on a different browser (not sharing the localcache), see there is no way to load the active / previous sessions / projects!

This issue might be a duplicate of existing issues. Please check:
opencode webon a remote/headless server accessed via port forwarding, with sessions not appearing despite the API returning them correctly./api/sessionreturns sessions correctly.If your issue is specifically about accessing the UI from a different browser (not sharing localStorage), it aligns most closely with #45011, which has a detailed root-cause analysis and a workaround.
