The prompt
Using the existing rectangular base plate, add the core ankle mechanism. Add one vertical support exactly at the geometric center of the base. On top of this support, add a centered ball joint. Above the ball joint, add one rectangular mobile foot pedal centered directly over the ball joint, able to tilt in all directions. Add a simple front foot retainer on the pedal, like the front upper part of an open sandal or slipper, so a foot can slide underneath and stay secured. At the front of the pedal, add an engagement cross made of: * one horizontal bar with multiple holes; * one vertical bar with multiple holes. Keep the support, ball joint, and pedal center perfectly aligned. Create a clean, simple, mechanically realistic model.
