The sequence, densely
A first page of the jōyō list, most frequent first. Each cell is a KanjiVG diagram animated in stroke order. The full set is the gallery — paged, not vendored.
The argument
Speculative, and labeled as such. A two-slot frame can be likened to a two-argument operator. That likening is analogy.
Archive. Classifier packaging and VN-suru Argument Transfer stay on the archive desk.
Stroke diagrams: KanjiVG, Ulrich Apel et al., CC BY-SA 3.0. Twelve worked files are stored in this site. The gallery loads the rest from the KanjiVG repository at view time. Jōyō index fields (grade, frequency, stroke count) come from the kanji-data jōyō list.
