The component listens for `postMessage` events and displays span data in a responsive table format.\n\n## Features\n\n- **Message-based data handling**: Listens for `postMessage` events with span data\n- **Flexible schema**: Uses Zod for runtime validation of incoming messages\n- **Theme support**: Light/dark theme switching via settings messages\n- **Read-only mode**: Configurable read-only state\n- **Responsive design**: Mobile-friendly table with overflow handling\n- **Type safety**: Full TypeScript support with proper type inference\n\n## Message Schema\n\nThe component accepts two types of messages:\n\n### Data Messages\n```typescript\n{\n type: 'data',\n data: {\n span_id: string,\n input: unknown,\n output: unknown,\n expected: unknown,\n metadata: unknown | null\n }\n}\n```\n\n### Settings Messages\n```typescript\n{\n type: 'settings',\n settings: {\n theme: 'light' | 'dark',\n readOnly: boolean\n }\n}\n```\n\n## Usage\n\nThe component automatically starts listening for messages when mounted. To send data:\n\n```javascript\n// Send span data\nwindow.postMessage({\n type: 'data',\n data: {\n span_id: 'unique-id',\n input: 'Some input text',\n output: 'Generated output',\n expected: 'Expected output',\n metadata: { additional: 'info' }\n }\n}, '*');\n\n// Update settings\nwindow.postMessage({\n type: 'settings',\n settings: {\n theme: 'dark',\n readOnly: true\n }\n}, '*');\n```\n\n## Demo\n\nThe included demo provides buttons to:\n- Add sample span data\n- Toggle between light/dark themes\n- Toggle read-only mode\n\n## File Structure\n\n```\n├── backend/\n│ └── index.ts # Hono server for serving files\n├── frontend/\n│ ├── components/\n│ │ └── SpanTable.tsx # Main table component\n│ └── index.html # Demo page\n└── README.md\n```\n\n## Key Features\n\n1. **Flexible Data Handling**: The component can handle any data type in the span fields (string, number, object, etc.)\n2. **Safe Rendering**: All values are safely converted to strings for display\n3. **Metadata Formatting**: JSON metadata is pretty-printed for readability\n4. **Responsive Design**: Table scrolls horizontally on smaller screens\n5. **Error Handling**: Invalid messages are logged but don't crash the component\n\n## Technical Details\n\n- Built with React 18.2.0\n- Uses Zod for runtime schema validation\n- Styled with TailwindCSS\n- No external UI library dependencies (custom table components)\n- Fully typed with TypeScript",[139],"296c6800-9f1b-11f0-9265-0224a6c84d84","frontend","0109715d-524a-4f93-8660-cc6d79a3287e",2,["D",1759359945623],"directory",[146],"39e1b136-9f1b-11f0-acbe-0224a6c84d84","backend","5788af28-45ee-481b-b7b0-eb2c4899fe8a",4,["D",1759359973241],[153],"pulls","branches","forks","envVars",{"_165":60,"_167":60},"connections",{"_165":60,"_166":60},"count","unfilledCount","emptyCount",{"_41":152,"_31":153,"_29":154,"_131":-5,"_39":40,"_38":155,"_133":56,"_36":230,"_13":60,"_33":150,"_34":-5,"_23":24,"_136":-5,"_179":231,"_26":232},{"_41":223,"_31":224,"_29":54,"_131":154,"_39":40,"_38":211,"_133":24,"_36":225,"_13":132,"_33":226,"_34":227,"_23":24,"_136":-5,"_179":228,"_26":229},{"_41":145,"_31":146,"_29":147,"_131":-5,"_39":40,"_38":148,"_133":56,"_36":220,"_13":60,"_33":150,"_34":-5,"_23":24,"_136":-5,"_179":221,"_26":222},{"_41":216,"_31":215,"_29":208,"_131":147,"_39":40,"_38":148,"_133":56,"_36":217,"_13":60,"_33":150,"_34":-5,"_23":24,"_136":-5,"_179":218,"_26":219},{"_41":205,"_31":206,"_29":207,"_131":208,"_39":40,"_38":209,"_133":56,"_36":210,"_13":211,"_33":135,"_34":212,"_23":24,"_136":-5,"_179":213,"_26":214},{"_41":201,"_31":32,"_29":30,"_131":147,"_39":40,"_38":14,"_133":56,"_36":202,"_13":60,"_33":20,"_34":35,"_23":24,"_136":-5,"_179":203,"_26":204},{"_41":193,"_31":194,"_29":195,"_131":147,"_39":40,"_38":196,"_133":56,"_36":197,"_13":148,"_33":20,"_34":198,"_23":24,"_136":-5,"_179":199,"_26":200},{"_41":185,"_31":186,"_29":187,"_131":147,"_39":40,"_38":188,"_133":56,"_36":189,"_13":60,"_33":135,"_34":190,"_23":24,"_136":-5,"_179":191,"_26":192},{"_41":138,"_31":139,"_29":140,"_131":-5,"_39":40,"_38":141,"_133":24,"_36":182,"_13":60,"_33":20,"_34":143,"_23":24,"_136":-5,"_179":183,"_26":184},{"_41":128,"_31":129,"_29":130,"_131":-5,"_39":40,"_38":132,"_133":56,"_36":178,"_13":60,"_33":135,"_34":103,"_23":24,"_136":-5,"_179":180,"_26":181},["D",1759359816111],"children",[],[129],["D",1759359993013],[],[139],"5367507a-9f1b-11f0-918f-0224a6c84d84","test-messages.js","53675142-9f1b-11f0-918f-0224a6c84d84",7,["D",1759360016062],"// Test script to demonstrate sending messages to the SpanTable component\n// This can be run in the browser console or included in other applications\n\n// Sample span data that matches the expected schema\nconst sampleSpans = [\n {\n span_id: \"test-1\",\n input: \"An orphaned boy discovers he's a wizard on his 11th birthday when Hagrid escorts him to magic-teaching Hogwarts School.\",\n output: \"Harry Potter and the Philosopher's Stone\",\n expected: \"Harry Potter and the Sorcerer's Stone\",\n metadata: null\n },\n {\n span_id: \"test-2\", \n input: \"A young hobbit must destroy a powerful ring to save Middle-earth from the Dark Lord Sauron.\",\n output: \"The Lord of the Rings\",\n expected: \"The Fellowship of the Ring\",\n metadata: { genre: \"fantasy\", year: 1954, author: \"J.R.R.
