Tenjin is the deified Sugawara no Michizane, patron of scholarship. His attribute is the plum blossom.
Anyone learning a language or an instrument mostly practises by feel. Learning research is fairly clear about what consolidates memory: spaced repetition, active recall, enough sleep. None of it is visible. You cannot see what is stable and what is decaying again.
Tenjin should make that visible. Not as a bar chart, but as a picture of a net that thickens in some places and thins in others.
Still open. The approach only settles once it is clear where the learning data comes from. Until then any technical choice would be a guess.
No measured values yet. Once there is something to profile, this chapter will report frame rate at increasing node counts, time to first frame, and the browser's memory footprint over a session.
First settle which data actually shows progress. Without that the visualisation is decoration.
