Marble's 183 clusters give a ready-made middle zoom level (subject → domain cluster → topic) with pre-written parent copy — but cover only 5 of 8 subjects (none for Computing, Life Skills, Learning to Learn) and stop at age band 10.
Decide: (a) home-screen zoom level (proposal: domain clusters with mastery fill + a "ready now" strip); (b) author the ~30 missing clusters in Marble's style now, or hide uncovered subjects at MVP.
