wip(0.S2): migrate - a var nothing writes becomes a let; a state is keyed by its module, directory or program, so every program's plan agrees; paths normalized; program states named SceneDemoState / scene_demo_st; the LSP reads state, mut and entry/handler parameters

# text_fit.ludic - text-fit: shrink 12px draws a line that does not fit its box smaller, down to that

# px or em) spaces a text's lines. Both are inherited, as font properties are.
