Shows a continuous task trajectory being segmented by a discretization mapping f into an ordered sequence of atomic subtasks (τ1..τn). Each τ box has an explicit input/output interface and a measurable completion signal (metric bar). As subtasks complete in order, a reconstructed path in the bottom panel grows to approximate the original continuous task, illustrating composability and observability for learning.
Pure Canvas2D; responsive scaling via scale=min(w,h)/240; blocky grid snapping at 4px*scale; animation cycles ~3.8s with discrete step indexing plus eased within-step progress; no external dependencies.
