- src/diagram: plane (constructed points, graphs with computed roots, vertex, extrema, tangent, asymptotes, piecewise limits, regions, rotations and reflections, line from ax + by = c), number line with intervals and stacked fractions, solids with hidden edges, bar/line/pie charts, sign tables, Venn, arrow mappings, probability trees, fraction bars and mixed numbers, grids, groups, clock. Pure-math text is bidi-overridden: Persian digits used to turn 3 × 4 = 12 into 12 = 4 × 3 even with dir=ltr. - MathText locks math runs inside Persian sentences in chat bubbles and figure captions, so -1 no longer shows as 1-. - Family screen: a student sees only the invite-code form; the parent form is behind a link. - Dev-only diagram gallery at ?gallery (not in the production build).
