Open the app on your mobile device\n2. Tap the upload area to take a photo or select from gallery\n3. Wait for AI analysis (usually 3-5 seconds)\n4. Review the extracted event title and date\n5. Tap \"Add to Calendar\" to download the .ics file\n6. Open the downloaded file with your calendar app\n\n### For Developers:\n- The app automatically resizes large images on the client side\n- Photos are stored using Val Town's blob storage\n- AI extraction uses OpenAI's vision model with structured JSON output\n- Calendar files include the photo URL in the event description\n\n## Mobile Optimization\n\n- Touch-friendly interface with 44px minimum touch targets\n- Camera capture support with `capture=\"environment\"` attribute\n- Drag and drop support for desktop browsers\n- Responsive design that works on all screen sizes\n- Loading states and error handling for poor network conditions","children",[],[80],"806a49f6-9caa-11f0-a6b2-0224a6c84d84","shared","c4306f65-0021-4a8a-96b8-9ddc64a048fd",2,["D",1759091656118],[95],[89],{"_35":96,"_13":97,"_38":98,"_40":90,"_42":43,"_44":91,"_46":47,"_48":99,"_17":66,"_51":52,"_53":100,"_55":56,"_57":-5,"_85":101,"_18":102},"806a4276-9caa-11f0-a6b2-0224a6c84d84","types.ts","806a432a-9caa-11f0-a6b2-0224a6c84d84",["D",1759091656118],"export interface ExtractedEvent {\n title: string;\n date: string; // ISO date string\n photoUrl: string;\n photoId: string;\n}\n\nexport interface UploadResponse {\n success: boolean;\n event?: ExtractedEvent;\n error?: string;\n}\n\nexport interface CalendarEvent {\n title: string;\n date: string;\n photoUrl: string;\n}",[],[89,97],"b5ba3490-9caa-11f0-975e-0224a6c84d84","frontend","543c874c-b61a-42f9-bb22-1d20809564a8",8,["D",1759091745567],[110,111,112,113],[104],{"_35":137,"_13":138,"_38":139,"_40":105,"_42":43,"_44":140,"_46":47,"_48":141,"_17":66,"_51":73,"_53":-5,"_55":56,"_57":-5,"_85":142,"_18":143},{"_35":130,"_13":131,"_38":132,"_40":105,"_42":43,"_44":106,"_46":47,"_48":133,"_17":66,"_51":24,"_53":134,"_55":56,"_57":-5,"_85":135,"_18":136},{"_35":122,"_13":123,"_38":124,"_40":105,"_42":43,"_44":125,"_46":47,"_48":126,"_17":66,"_51":52,"_53":127,"_55":56,"_57":-5,"_85":128,"_18":129},{"_35":114,"_13":115,"_38":116,"_40":105,"_42":43,"_44":117,"_46":47,"_48":118,"_17":66,"_51":24,"_53":119,"_55":56,"_57":-5,"_85":120,"_18":121},"bad247ba-9caa-11f0-8ec8-0224a6c84d84","style.css","bad24918-9caa-11f0-8ec8-0224a6c84d84",9,["D",1759091754056],"/* Additional custom styles */\n\n/* Ensure proper mobile touch targets */\nbutton, input[type=\"file\"] {\n min-height: 44px;\n}\n\n/* Hide file input visually but keep it accessible */\n.file-input-hidden {\n position: absolute;\n width: 1px;\n height: 1px;\n padding: 0;\n margin: -1px;\n overflow: hidden;\n clip: rect(0, 0, 0, 0);\n white-space: nowrap;\n border: 0;\n}\n\n/* Error message styling */\n.error-message {\n background-color: #fed7d7;\n color: #c53030;\n padding: 1rem;\n border-radius: 0.5rem;\n margin: 1rem 0;\n border-left: 4px solid #e53e3e;\n}\n\n/* Success message styling */\n.success-message {\n background-color: #c6f6d5;\n color: #2d7d32;\n padding: 1rem;\n border-radius: 0.5rem;\n margin: 1rem 0;\n border-left: 4px solid #38a169;\n}\n\n/* Mobile-specific adjustments */\n@media (max-width: 640px) {\n .container {\n padding: 0.5rem;\n }\n \n .event-card {\n padding: 1rem;\n }\n \n h1 {\n font-size: 1.5rem;\n }\n \n h2 {\n font-size: 1.25rem;\n }\n}",[],[104,115],"d9181312-9caa-11f0-9795-0224a6c84d84","index.tsx","d91813b2-9caa-11f0-9795-0224a6c84d84",13,["D",1759091804899],"/** @jsxImportSource https://esm.sh/react@18.2.0 */\nimport React from 'https://esm.sh/react@18.2.0?deps=react@18.2.0';\nimport { createRoot } from 'https://esm.sh/react-dom@18.2.0/client?deps=react@18.2.0';\nimport App from './components/App.tsx';\n\nconst root = createRoot(document.getElementById('root')!);\nroot.render();",[],[104,123],"b5ba273e-9caa-11f0-975e-0224a6c84d84","index.html","b5ba27de-9caa-11f0-975e-0224a6c84d84",["D",1759091745567],"\n\n\n \n \n Event Extractor\n \n \n \n \n\n\n
