### **🔧 Human Testing Fixes Applied**

**Issues Identified:**

   - `revealSeed()` - Extracted `@click="showSeed = true"`
   - `copySeedPhrase()` - Extracted complex seed phrase clipboard operation
   - `copyDerivationPath()` - Extracted complex derivation path clipboard operation

2. **Added Missing Computed Property:**
   - `helpButtonClass()` - Extracted lengthy help button styling

3. **Template Updates:**
   - Replaced all inline click handlers with method calls
   - Replaced lengthy CSS class with computed property binding
   - Maintained all existing functionality and styling
