*(Ολόκληρη η λογική της εφαρμογής: theme toggle, form validation, skill list toggle, και τα δύο API calls)*

```javascript
// --- Element Selectors ---

// --- 1. Theme Toggler ---

// --- 3. Contact Form Validation ---

    }
}

    }
}

// --- Event Listeners & Initial Calls ---
if(newQuoteBtn) {
    newQuoteBtn.addEventListener('click', getQuote);
}

// Initial calls when the page loads
document.addEventListener('DOMContentLoaded', () => {
    loadPortfolioImages();
