The folded grid

Make an 8-second landscape seamless 3D-style loop titled exactly 'The folded grid'. A small wireframe grid gently folds into a shallow wave, then returns to a flat field. Use a fixed camera, charcoal lines on a cool-neutral field and a single coral guide edge. Calculate a periodic deformation so frame zero and the end agree; do not fetch textures, shaders, libraries or models. The mood should be patient and architectural. First supply a beat sheet and four keyframes, then one deterministic HTML file with window.DURATION = 8 and async window.seek(t).
