 ### TypeScript Conventions
-
 - Use explicit types for props and function parameters
 - Use `any` sparingly; prefer union types or interfaces
 - Define column indices in a centralized `COLUMNS` object (see `src/types.ts`)
 
 ```typescript
-// Good
 interface ProductDescriptionsProps {
   data: ExcelRow[];
   onEdit: (index: number) => void;
 }
 
-// Good - centralized constants

 ### React Patterns
-
 - Destructure props in function signature
 - Use `useMemo` for expensive computations
 - Use `useCallback` for event handlers passed to child components
 - Keep `useState` calls at the top of component
 
-```typescript
-export function ProductDescriptions({ data, onEdit }: ProductDescriptionsProps) {
-  const [activeTab, setActiveTab] = useState<TabType>('all');
-  const [search, setSearch] = useState('');
-
-  const filteredData = useMemo(() => {
-    // expensive computation
-  }, [data, activeTab, search]);
-}
-```
-
 ### Error Handling
-
 - Use TypeScript's type system for runtime safety
 - Use optional chaining (`?.`) and nullish coalescing (`??`)
 - Validate file uploads with proper type checks
 
-```typescript
-const file = e.target.files?.[0];
-if (!file) return;
-
-// Validate Excel data
-if (data.length > 0) {
-  const rawHeaders = data[0];
-  const rawRows = data.slice(1);
-}
-```
-
 ### UI/Styling
-
 - Use Tailwind CSS for all styling
 - Use `cn()` utility from `lib/utils` for conditional classes
 - Follow existing color scheme (slate, blue, green, red for status)
 - Use `lucide-react` for icons
-- Keep responsive design in mind
 
 ```typescript
-import { cn } from '../lib/utils';
-
-<button
-  className={cn(
-    "px-4 py-2 rounded-md text-sm font-medium",
-    isActive 
-      ? "bg-blue-600 text-white" 
-      : "bg-slate-800 text-slate-400"
-  )}
->
+<button className={cn("px-4 py-2 rounded-md", isActive ? "bg-blue-600" : "bg-slate-800")}>

 ### Data Processing
-
-- When processing Excel data, handle both string and number types
+- Handle both string and number types when processing Excel data
 - Use centralized column index constants
 - Format numbers consistently (2 decimal places for prices/weights)
-- Handle Excel date serial numbers properly (convert to readable dates)
+- Handle Excel date serial numbers properly
 
 ```typescript
 // Handle date columns from Excel
-if (header.includes('date') || header.includes('launch')) {
 if (typeof val === 'number' && val >= 25569 && val <= 60000) {
   const excelEpoch = new Date(1899, 11, 30);
-    const date = new Date(excelEpoch.getTime() + val * 86400000);
-    return date.toLocaleDateString('en-GB');
-  }
+  return new Date(excelEpoch.getTime() + val * 86400000).toLocaleDateString('en-GB');
 }
 ```
 
 ### Git Workflow
-
 - Make small, focused commits
 - Write clear commit messages describing what changed
 - Push to main to trigger Vercel deployment automatically
 
-### Running Single Components
-
-When testing or developing specific features:
-```bash
-npm run dev    # Start dev server - access at http://localhost:3000
-```
-
 ### Environment Variables
-
 - Use `.env` file for local development
 - Never commit secrets - use Vercel dashboard for production env vars
 
-Required environment variables (production):
-- `VITE_SUPABASE_URL`
-- `VITE_SUPABASE_ANON_KEY`
-- `VITE_GEMINI_API_KEY`
-- `VITE_ANTHROPIC_API_KEY`
+Required: `VITE_SUPABASE_URL`, `VITE_SUPABASE_ANON_KEY`, `VITE_GEMINI_API_KEY`, `VITE_ANTHROPIC_API_KEY`
