Val Town runs on Deno in a serverless context, not Node.js\n - Code in `shared/` must work in both frontend and backend environments\n - Cannot use `Deno` keyword in shared code\n - Use `https://esm.sh` for imports that work in both environments\n\n2. **SQLite Peculiarities:**\n - Limited support for ALTER TABLE operations\n - Create new tables with updated schemas and copy data when needed\n - Always run table creation before querying\n\n3. **React Configuration:**\n - All React dependencies must be pinned to 18.2.0\n - Always include `@jsxImportSource https://esm.sh/react@18.2.0` at the top of React files\n - Rendering issues often come from mismatched React versions\n\n4. **File Handling:**\n - Val Town only supports text files, not binary\n - Use the provided utilities to read files across branches and forks\n - For files in the project, use `readFile` helpers\n\n5. **API Design:**\n - `fetch` handler is the entry point for HTTP vals\n - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`\n - Properly handle CORS if needed for external access",[],[158,192],[158],{"_105":201,"_95":202,"_159":203,"_161":-5,"_162":142,"_163":164,"_165":119,"_107":204,"_101":32,"_167":168,"_169":-5,"_170":22,"_171":-5,"_172":205,"_99":344},"78908c02-09b3-11f0-bd40-569c3dd06744","frontend","73ef012d-a619-426c-9214-4298e40b3f6a",["D",1742932687486],[206,222,321,336],{"_105":207,"_95":208,"_159":209,"_161":203,"_162":142,"_163":210,"_165":119,"_107":211,"_101":32,"_167":168,"_169":-5,"_170":22,"_171":-5,"_172":212,"_99":221},"80c1d50c-09b3-11f0-93f8-569c3dd06744","assets","1a3c8484-433b-434c-8d39-921c0db04f37",2,["D",1742932701239],[213],{"_105":214,"_95":215,"_159":216,"_161":209,"_162":142,"_163":210,"_165":119,"_107":217,"_101":32,"_167":195,"_169":218,"_170":22,"_171":-5,"_172":219,"_99":220},"80c1b41e-09b3-11f0-93f8-569c3dd06744","sample-svg.svg","80c1b4fa-09b3-11f0-93f8-569c3dd06744",["D",1742932701239],"",[],[202,208,215],[202,208],{"_105":223,"_95":224,"_159":225,"_161":203,"_162":142,"_163":164,"_165":119,"_107":226,"_101":32,"_167":168,"_169":-5,"_170":22,"_171":-5,"_172":227,"_99":320},"78906c7c-09b3-11f0-bd40-569c3dd06744","components","5bc07707-5da8-4f5b-8662-0819d51b1c74",["D",1742932687486],[228,238,246,255,263,271,279,287,295,303,311],{"_105":229,"_95":230,"_159":231,"_161":225,"_162":142,"_163":232,"_165":22,"_107":233,"_101":234,"_167":179,"_169":235,"_170":22,"_171":-5,"_172":236,"_99":237},"50b49114-09b4-11f0-99d7-569c3dd06744","App.tsx","499739fe-957d-43cd-bddf-99b876d8c427",9,["D",1742933050117],4,"/** @jsxImportSource https://esm.sh/react@18.2.0?dev */\nimport { useLocalStorage } from \"https://esm.sh/react-use?dev&deps=react@18.2.0&react-dom@18.2.0\";\nimport React, { useState, useEffect } from \"https://esm.sh/react@18.2.0?dev\";\nimport { Login } from \"./Login.tsx\";\n\nexport function App() {\n const [bearerToken, setBearerToken] = useLocalStorage(\"bearer\", \"\");\n const [error, setError] = useState(null);\n \n // Add some logging to help debug\n useEffect(() => {\n console.log(\"App component mounted\");\n console.log(\"Bearer token exists:\", Boolean(bearerToken));\n \n // Check if localStorage is working\n try {\n localStorage.setItem('test', 'test');\n const test = localStorage.getItem('test');\n console.log(\"LocalStorage test:\", test === 'test' ?
