- **Features:**
  - Responsive image handling with proper aspect ratios
  - Lazy loading support via `loading="lazy"`
  - Hover effects: lift animation, glow effect, shadow expansion
  - Dark/light mode support with CSS variables
  - WCAG AA accessible (proper semantic HTML, alt text)
  - Tested at all breakpoints (320px, 768px, 1060px+)

### ✅ Navigation Header

- **Features:**
  - Logo respects current language context (IT → `/it/`, EN → `//`)
  - Language switcher dropdown with smooth transitions
  - Theme toggle (dark ↔ light) with instant visual feedback
  - Responsive design (hamburger on mobile, full nav on desktop)
  - Keyboard accessible (Tab, Enter, Escape)
  - Alpine.js powered for interactivity

### ✅ Hamburger Menu (Mobile)

  - Mobile-first design (visible only < 768px)
  - Smooth animations (GPU-accelerated)
  - Keyboard accessible (Escape to close)

### ✅ Breadcrumb Navigation
- **Component:** Hierarchical navigation showing content path
- **Features:**

  - Semantic HTML5 `<nav>` and `<ol>` elements
  - Language-aware links maintain context when clicked
  - Proper styling and hover states
  - Renders correctly on all article pages
  - Fixed Hugo layout lookup issue (was using `_default/single.html`, now properly targets `articles/single.html`)

### ✅ Responsive Design Verified
- ✅ Mobile (320px): Hamburger menu active, single-column layout
- ✅ Tablet (768px): Transition zone, navigation adjusts
- ✅ Desktop (1060px+): Full header nav visible, hamburger hidden
- ✅ All interactions tested on multiple screen sizes

## 📝 Key Bug Fixes

### Breadcrumb Rendering Issue (RESOLVED)
**Problem:** Breadcrumb partial existed but produced zero HTML output.
**Root Cause:** Hugo layout lookup was using `layouts/_default/single.html` instead of `layouts/articles/single.html`.
**Solution:** Added breadcrumb partial call to the actual layout file being used.

### Logo Link Regression (RESOLVED)
**Problem:** Header logo link was hardcoded to `/`, breaking Italian navigation.
**Root Cause:** Language context not respected in header template.
**Solution:** Updated logo link to use `.Params.Lang` → `/it/` for Italian, `/` for English.
