🧊 Neon Tesseract Rotation Visualiser: Six-Plane 4D Rotation, Projections, Slice and Net Fold

Rotate a 4D hypercube in all six planes (xw, yw, zw plus xy, xz, yz), see its 16 vertices, 32 edges, 24 faces and 8 cells as a glowing 3D projection, four 2D projections, a vertex graph, a live w = c slice, the Dali-cross net that folds into 4D, and the live 4D vertex table, with a Pfaffian readout and missions.
