Vite vanilla-JS single-page app with two tabs (Turing, Post) running
the user's machine code in a Web Worker. Includes a virtualized UI
belt with mask-fade edges and slide animation, an interactive control
panel (alphabet picker + L/S/R movement + Apply), an auto-running
demo mode with Take control, single-step / continuous-run / paced
auto-step modes, and a log panel.

Depends on the published @turing-machine-js/machine and
@post-machine-js/machine v3 packages.
