199- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites
200- For persistence, use Val Town SQLite or Blob storage with `import.meta.url` for keys/table names
201- **React Configuration:** When using React libraries, pin versions with `?deps=react@18.2.0,react-dom@18.2.0` and include the `@jsxImportSource` pragma
202- When facing client-side render issues, check if all React dependencies are pinned to the same version
203- **Styling:** Default to using TailwindCSS via `<script src="https://cdn.twind.style" crossorigin></script>` unless otherwise specified

263### Frontend Best Practices
264- Structure as a standard client-side React app
265- Use SVG for favicons (Val Town only supports text files)
266- Separate components into individual files
267- Access bootstrapped data from `window.__INITIAL_DATA__`
268- Use React 18.2.0 consistently in all imports and the `@jsxImportSource` pragma
269- Follow the React component pattern from the example project
270- Handle API calls properly with proper error catching
271
289   - Always run table creation before querying
290
2913. **React Configuration:**
292   - All React dependencies must be pinned to 18.2.0
293   - Always include `@jsxImportSource https://esm.sh/react@18.2.0` at the top of React files
294   - Rendering issues often come from mismatched React versions
