Memory Match Cards: A memory card game with 16 cards featuring simple CSS-drawn icons. Cards flip in 3D on click; matched pairs stay revealed with a sparkle and mismatches flip back after a second. Show a move counter, a timer, a star rating and a shuffle/restart button. 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.
