The builtin logo, or a text file in logo syntax, drawn as an extruded slab: the front is the art as it is, the back is the art mirrored, and the side walls are shaded with block glyphs. Rendering is pure: no terminal, no input, no timer. `--logo-type spin` hands every frame to the normal logo pipeline, so the modules are laid out beside it exactly as they are for any other type, and the first frame without --watch is byte-identical to the same art printed as a builtin logo. The rotation is driven by the `--watch` loop: `ffSpinTick()` runs once per refresh and `ffLogoPrint()` is called only when it reports a step, so the logo and the modules can never drift apart, and a build that never uses the type costs one comparison per refresh. Speed is set either as degrees per frame (--logo-spin-speed-per-frame, default 10) or as seconds per revolution (--logo-spin-speed-per-round, read from the clock and winning over the former when both are given). Both take negative values to turn the other way, and --logo-spin-angle picks the frame to start from.
