The prompt

Tidal Moiré: Two overlapping sets of fine concentric circles, one fixed and one following the mouse, producing shifting moiré interference patterns in black and white. A slider changes line spacing, a toggle switches to straight-line grids, and clicking freezes the moving set in place. 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.
