shared elements web inspector

[spencerc99]

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.
