+    "prompt": "Build a single self-contained HTML file: a luxury 8-fold damask KALEIDOSCOPE for a wallcovering brand. Improve on a prior version with these MANDATORY design fixes: (1) Add a fixed 56px top-bar (z-index above the canvas) with the DW wordmark left-aligned in Cormorant Garamond serif, white, uppercase, letter-spacing .18em, plus a palette-name pill on the right and a subtle 'click to shift palette' hint. (2) The radial motif MUST read as a real damask leaf/urn form built with bezierCurveTo anchor points (NOT amoeba blobs) — apply the kaleidoscope oscillation to those bezier anchors. (3) High-contrast Royal palette: near-black ground #0d0b07, champagne #EDE0C4, crisp gold petals #C8A951, carmine secondary bloom #B5335A — keep petal vs ground hue contrast 60°+ so it pops (no muddy warm beige). Mouse-warp symmetry, click cycles palettes, center gold sheen, vignette overlay, 60fps canvas. Output ONLY the HTML.",
