Web inspector page (recommended)
- Input a URL → we compute the room, connect read-only, and display:
- Computed room ID, PartyKit host, connection status
- All shared source elements (elementId, permissions)
- Copyable data-source strings and ready-to-paste HTML/React snippets
- Live value preview of each element
- Bonus: “probe this page” button for the current tab; “normalize my data-source” copy action.
