Open multiple browser tabs or share the URL with others to see multiple cursors in real-time!\n\n### Debug Features\n\n- **Show/Hide Logs**: Click the \"Show Logs\" button to see detailed connection progress and debug information\n- **Error Logging**: All errors are caught and displayed in the log panel for easy debugging\n- **Mobile Testing**: Touch and drag gestures work on mobile devices for cursor sharing\n\nThe debug logs show:\n- Peer registration and discovery\n- WebRTC connection states (connecting, connected, disconnected)\n- Data channel status\n- ICE candidate exchanges\n- Any errors that occur during the process","deleted",false,"label",[37],"6e4f20ba-84d2-11f0-8c5f-0224a6c84d84","frontend","fbd7379b-b748-465c-9284-a94b081a9e35",["D",1756469977706],0,"directory",[58],"d5432470-84d1-11f0-aaf4-0224a6c84d84","backend","95adb4b3-d052-4e19-9770-4d3664b9cb76",1,["D",1756469720936],[65],{"_35":64,"_13":65,"_38":66,"_40":-5,"_41":42,"_43":67,"_45":46,"_47":100,"_17":61,"_50":62,"_51":-5,"_53":54,"_55":-5,"_74":101,"_18":102},{"_35":57,"_13":58,"_38":59,"_40":-5,"_41":42,"_43":49,"_45":46,"_47":77,"_17":61,"_50":62,"_51":-5,"_53":54,"_55":-5,"_74":78,"_18":79},{"_35":36,"_13":37,"_38":39,"_40":-5,"_41":42,"_43":44,"_45":46,"_47":73,"_17":49,"_50":24,"_51":52,"_53":54,"_55":-5,"_74":75,"_18":76},["D",1756470387355],"children",[],[37],["D",1756469977706],[80,81],[58],{"_35":92,"_13":93,"_38":94,"_40":59,"_41":42,"_43":95,"_45":46,"_47":96,"_17":49,"_50":24,"_51":97,"_53":54,"_55":-5,"_74":98,"_18":99},{"_35":82,"_13":83,"_38":84,"_40":59,"_41":42,"_43":85,"_45":46,"_47":86,"_17":87,"_50":88,"_51":89,"_53":54,"_55":-5,"_74":90,"_18":91},"a9bf461a-84d3-11f0-b269-0224a6c84d84","webrtc.js","843e64c6-84d2-11f0-ac66-0224a6c84d84",24,["D",1756470506926],15,"script","class WebRTCMouseDemo {\n constructor() {\n this.peerId = this.generatePeerId();\n this.peers = new Map(); // peerId -> RTCPeerConnection\n this.cursors = new Map(); // peerId -> cursor element\n this.lastMouseUpdate = 0;\n this.mouseThrottle = 50; // ms\n this.ownCursor = null;\n this.logs = [];\n this.maxLogs = 50;\n \n this.setupLogging();\n this.init();\n }\n \n generatePeerId() {\n return Math.random().toString(36).substr(2, 9);\n }\n \n setupLogging() {\n // Override console methods to capture logs\n const originalLog = console.log;\n const originalError = console.error;\n const originalWarn = console.warn;\n \n console.log = (...args) => {\n this.addLog('LOG', args.join(' '));\n originalLog.apply(console, args);\n };\n \n console.error = (...args) => {\n this.addLog('ERROR', args.join(' '));\n originalError.apply(console, args);\n };\n \n console.warn = (...args) => {\n this.addLog('WARN', args.join(' '));\n originalWarn.apply(console, args);\n };\n \n // Catch unhandled errors\n window.addEventListener('error', (event) => {\n this.addLog('ERROR', `Unhandled error: ${event.error?.message || event.message}`);\n });\n \n window.addEventListener('unhandledrejection', (event) => {\n this.addLog('ERROR', `Unhandled promise rejection: ${event.reason}`);\n });\n \n // Setup log panel controls\n document.addEventListener('DOMContentLoaded', () => {\n const clearBtn = document.getElementById('clear-logs');\n \n if (clearBtn) {\n clearBtn.addEventListener('click', () => {\n this.clearLogs();\n });\n }\n });\n }\n \n addLog(level, message) {\n const timestamp = new Date().toLocaleTimeString();\n const logEntry = { level, message, timestamp };\n \n this.logs.push(logEntry);\n if (this.logs.length > this.maxLogs) {\n this.logs.shift();\n }\n \n this.updateLogDisplay();\n }\n \n updateLogDisplay() {\n const logContent = document.getElementById('log-content');\n if (!logContent) return;\n \n const logHtml = this.logs.map(log => {\n const color = log.level === 'ERROR' ?
