franky-adl/3d-wave-grid ? reverse-engineered prompt

Build me an interactive 3D landing page with a grid of little cubes that feels alive and reacts to the mouse with smooth wave and ripple motion. I want it to look polished and modern, with the motion being the main focus, and it should run fast without feeling heavy.

Use a 3D scene with custom shader driven effects so the cubes can rise, fall, and distort in a fluid way as the pointer moves around. Add some subtle animation so it still looks interesting when the mouse is still. If it helps during development, include a simple debug panel for tweaking the effect live.

Make it easy to run locally and build for production, and keep the code clean enough that I can change colors, intensity, and movement later. If you need current docs for the libraries, look them up online.
