# Fixed! - Navigation Links Now Working

## Issue
Links weren't rendering in the sidebar.

## Root Cause
- `router.php` wasn't passing `$current_section` to the template  
- `partials/sidebar.php` was trying to use an undefined `$parts` variable
- `js/enhance.js` had issues with event delegation

## Solution Applied

### 1. Fixed router.php
```php
// Added this line to store current section
$current_section = $section;

// Fixed parts array parsing
$parts = array_values(array_filter(explode('/', trim($path, '/'))));
```

### 2. Fixed partials/sidebar.php
```php
// Now properly uses $current_section from router
$current_section = isset($current_section) ? $current_section : 'home';
```

### 3. Rewrote js/enhance.js
- Simplified event handling
- Better error handling
- Proper delegation for data-section attributes
- Works with current DOM structure
