/* Code Repulsion & Territory Competition. Layout: title with the three scenarios; the learning-cycle bar with scrubber
   and status; the 3D hidden-space stage beside the lateral-weight matrix and the pair inspector; then the Hamming
   radar, the cosine spectrum and the territory gauge. Changing text has a fixed size, so nothing moves while it runs. */
