## 🚨 Critical Issues Identified

### 1. CSS Loading System Bug
**Severity:** HIGH  
**Issue:** Plugin references non-existent `hvac-login.css` file  
**Location:** `includes/class-hvac-scripts-styles.php:1226`  
**Impact:** Login pages missing proper styling  
**Current Workaround:** Inline CSS in template files  
**Recommended Fix:** Update `enqueue_login_assets()` to load existing CSS files

```php
// CURRENT (BROKEN):
wp_enqueue_style('hvac-login', HVAC_PLUGIN_URL . 'assets/css/hvac-login.css');

// RECOMMENDED FIX:
wp_enqueue_style('hvac-community-login', HVAC_PLUGIN_URL . 'assets/css/community-login.css');
wp_enqueue_style('hvac-community-login-enhanced', HVAC_PLUGIN_URL . 'assets/css/community-login-enhanced.css');
```

### 2. CSS Files Not Being Enqueued
**Severity:** MEDIUM  
**Issue:** Valid CSS files exist but aren't being loaded by WordPress  
**Files:** `community-login.css`, `community-login-enhanced.css`  
**Impact:** Suboptimal styling, reliance on inline CSS
