+# Coding Style
+
+## Immutability (CRITICAL)
+
+ALWAYS create new objects, NEVER mutate:
+
+```javascript
+// WRONG: Mutation
+function updateUser(user, name) {
+  user.name = name  // MUTATION!
+  return user
+}
+
+// CORRECT: Immutability
+function updateUser(user, name) {
+  return {
+    ...user,
+    name
+  }
+}
+```
+
+## File Organization
+
+MANY SMALL FILES > FEW LARGE FILES:
+- High cohesion, low coupling
+- 200-400 lines typical, 800 max
+- Extract utilities from large components
+- Organize by feature/domain, not by type
+
+## Error Handling
+
+ALWAYS handle errors comprehensively:
+
+```typescript
+try {
+  const result = await riskyOperation()
+  return result
+} catch (error) {
+  console.error('Operation failed:', error)
+  throw new Error('Detailed user-friendly message')
+}
+```
+
+## Input Validation
+
+ALWAYS validate user input:
+
+```typescript
+import { z } from 'zod'
+
+const schema = z.object({
+  email: z.string().email(),
+  age: z.number().int().min(0).max(150)
+})
+
+const validated = schema.parse(input)
+```
+
