## Bug Report

### Environment
- **Browser:** Chrome
- **OS:** macOS

### Description
File upload fails silently for files over 10MB.

### Steps to Reproduce
1. Click upload button
2. Select a file larger than 10MB
3. Click submit
4. Observe: nothing happens, no error displayed

### Expected Behavior
File uploads successfully, OR clear error message is shown explaining the size limit.

### Actual Behavior
No feedback—upload silently fails.

### Additional Context
Smaller files upload correctly. Issue appears to be specific to file size validation.

## Summary
Implements rate limiting for API endpoints to prevent abuse and ensure fair usage.

## Changes
- Added rate limiting middleware using Redis store
- Default limit: 100 requests/minute/user
- Rate limit headers added to responses
- Updated API documentation with rate limit info

## Technical Details
- **Store:** Redis (for distributed rate limiting)
- **Algorithm:** Sliding window
- **Configurable:** Via environment variables

## Testing
- [x] Unit tests for rate limiting middleware
- [x] Integration tests with Redis
- [x] Manual testing of limit enforcement

## Reviewer Notes
Please review:
- Redis configuration in `config/redis.js`
- Error response format in rate limit exceeded cases

## Checklist
- [x] Tests added/updated
- [x] Documentation updated
- [x] No breaking changes

### Suggestion: Consider separating concerns

This function currently handles three responsibilities:
1. Data fetching
2. Data transformation
3. Database persistence

**Recommendation:** Split into separate functions:

```javascript
async function fetchUserData(userId) { ... }
function transformUserData(rawData) { ... }
async function saveUser(userData) { ... }
```

**Benefits:**
- Easier to test each function in isolation
- Clearer error handling per operation
- More reusable components

**Also:** The catch-all error handling could be more specific—consider catching specific error types to provide better error messages and recovery options.

Happy to discuss this approach if you'd like!

## Feature Request: Dark Mode Support

### Motivation
Many developers work during evening hours. The current bright UI causes eye strain during extended nighttime sessions.

### User Story
As a user, I want a dark mode option so I can use the application comfortably in low-light environments.

### Requirements
- [ ] Dark color scheme for all UI components
- [ ] System preference detection (auto-switch)
- [ ] Manual toggle in user settings
- [ ] Persist preference across sessions

### Scope
- Dashboard
- Settings pages
- Documentation/help pages
- All modals and popovers

### Acceptance Criteria
- [ ] No flickering on page load
- [ ] Smooth transition between modes
- [ ] All text remains readable
- [ ] Charts/graphs adapt to dark mode
