+# Floating Compact Layout
+
+Minimalist UI for Compact Mode — uses Zen colors, centers URL bar, and removes visual clutter.
+
+---
+
+## Requirement
+
+This mod requires both **Compact Mode** and a **compatible browser layout** — it will not work with Zen’s default settings.
+
+**To enable Compact Mode:**
+
+① Left-click the navigation bar
+
+② Click “Compact Mode”
+
+③ Select “Enable Compact Mode”
+
+**Browser layout requirement:**
+
+Go to Settings → Browser Layout and select either “Multiple Toolbars” or “Collapsed Toolbar”.
+The “Single Toolbar” layout is not supported and will prevent the mod from working properly.
+
+## 🌟 Features
+
+- 🔳 **Floating, compact URL bar**
+- 🧱 **Vertically centered, compact sidebar**
+- 🎨 **Applies the official Zen color palette**
+- ✂️ **Removes unnecessary labels and buttons for a cleaner interface**
+- 🖱️ **Sidebar and toolbar appear on hover for quick access**
+- 🚀 **Fully compatible with Zen Browser's Compact Mode**
+
+---
+
+## 💻 Toolbar Customization (macOS & Windo
