The prompt

Mortgage Calculator: A clean mortgage calculator: inputs for price, deposit, interest rate and term. It shows the monthly payment, total interest, and an animated donut of principal versus interest, plus a scrollable amortisation table by year. Every value updates live as sliders move. Build it as ONE self-contained HTML file: inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files); anything visual or audible is made in code (HTML/CSS, SVG, Canvas, WebGL or WebAudio). It must work when opened directly from disk, fit the browser window responsively, and run without console errors. Output ONLY the complete HTML file, starting with <!DOCTYPE html> and ending with </html>, with no explanation or markdown fences.
