The prompt

Color Palette Studio: A palette generator: press space to generate five harmonious colours (choose analogous, complementary, triadic or monochrome), click a swatch to lock it, and show each colour's HEX, RGB and a WCAG contrast rating against white and black. Clicking a code copies it with a toast. 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.
