### 4. Database Storage

**What's Stored:**
All homepage settings are saved to the `site_settings` table in PostgreSQL:

```sql
Key: 'homepage'
Settings JSON Structure:
{
  "hero": {
    "enabled": true/false,
    "headline": "string",
    "subheading": "string",
    "description": "HTML string from Quill",
    "ctaText": "string",
    "ctaLink": "string",
    "backgroundUrl": "/uploads/...",
    "layout": "text-left|text-center|text-right"
  },
  "promotion": {
    "enabled": true/false,
    "title": "string",
    "description": "HTML string from Quill",
    "imageUrl": "/uploads/...",
    "imagePosition": "left|center|right",
    "textAlignment": "left|center|right"
  },
  "portfolio": {
    "enabled": true/false,
    "title": "string",
    "description": "HTML string from Quill",
    "count": number (3-12)
  }
}
```

**API Endpoints:**

**Admin (Write):**

- `POST /api/admin/homepage/settings` - Save homepage settings
- Requires authentication
- Accepts JSON body with settings structure above

**Public (Read):**

- `GET /api/public/homepage/settings` - Fetch homepage settings
- No authentication required
- Returns settings for frontend display

### 5. Frontend Integration

**What Changed in home.html:**

- Added IDs to all homepage elements
- Created `loadHomepageSettings()` function
- Dynamically updates content from database

- Shows/hides sections based on enabled status

**Dynamic Elements:**

- Hero headline, subheading, description, CTA text/link, background
- Promotion title, description, image
- Portfolio title, description
- Text alignment, image positions, layouts

**How It Works:**

1. Page loads
2. Fetches `/api/public/homepage/settings`
3. Applies all settings to page elements
4. Updates content and styling dynamically
5. Sections auto-hide if disabled

## Technical Details

### Media Library Modal

The media library opens in an iframe modal with these features:

- Full-screen modal with close button
- Loads existing media library interface
- Passes selection back to parent window
- Security: validates message origin
- Closes automatically after selection

**Implementation:**

```javascript
function openMediaLibrary(section, field) {
  // Creates modal backdrop
  // Creates iframe with media library
  // Sets up message listener
  // Handles selection callback
}
```

### Quill Editor Initialization

```javascript
quillEditors.hero = new Quill('#heroDescription', {
  theme: 'snow',
  modules: { toolbar: toolbarOptions },
  placeholder: 'Enter hero section description...'
});
```

**Retrieving Content:**

```javascript
quillEditors.hero.root.innerHTML  // Gets HTML
```

**Setting Content:**

```javascript
quillEditors.hero.root.innerHTML = savedContent;
```

### Save Process

1. Collect all form data
2. Get HTML from Quill editors
3. Get layout settings from data attributes
4. Get media URLs from hidden inputs
5. Build settings object
6. POST to `/api/admin/homepage/settings`
7. Database updates via UPSERT query
8. Success notification

### Frontend Load Process

1. Page loads
2. `loadHomepageSettings()` called
3. Fetches from `/api/public/homepage/settings`
4. `applyHomepageSettings()` updates DOM
5. Sections shown/hidden based on enabled status
6. Content replaced with admin settings
7. Styles applied (alignment, layout)
