## Beschrijving

**SmoothPreview** brings modern app-style loading placeholders to your WordPress
and WooCommerce media galleries.

Instead of displaying blank white boxes or causing sudden vertical jumps while images
download, SmoothPreview calculates the photo’s exact dominant RGB color and locks
image aspect ratio server-side to guarantee **0 Cumulative Layout Shift (0 CLS)**.

#### Key Features

 * 🎨 **Adaptive Dominant Color Extraction**: Instantly samples photo colors in 
   less than 1 millisecond.
 * ⬛ **Classic Light Grey Skeleton Box**: Clean minimal loading placeholder mode.
 * ✨ **5 Shimmer Motion Directions**: Horizontal (LTR/RTL), Vertical (TTB/BTT),
   and Diagonal wave flashes.
 * 📐 **0 Layout Shift (CLS Prevention)**: Hard-locks image container aspect ratios.
 * 🛡️ **Admin Workflow Bypass**: Automatically bypasses preview effects while editing
   pages in WP Admin.
 * 🌙 **Auto Dark Mode**: Detects visitor dark mode preferences automatically.
 * ⚡ **Ultra Lightweight**: Zero external library dependencies, 100% PHP & CSS 
   native.

## Installatie

 1. Upload the `smooth-preview` directory to `/wp-content/plugins/`.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. Go to **Settings > SmoothPreview** to customize your preferred shimmer direction
    and placeholder style.
