Practise the systems

The eleven biological systems from souls, laid out as a living body you arrange by hand.

Stage 1 · Place. The eleven systems start fanned open on the left — click or drag each into a placeholder. Click a placed one to send it back. When all are down, press Next stage — this locks the placements and removes Clear board.
Stage 2 · Reasons. Where a row's left+right (or the centroid) are placed, a smiley appears in the middle — click it and that pair of systems blows up ×3 with a line drawn between them, while you write a reason; it collapses on save. Click the centroid's smiley to draw confluence arrows from its row's left & right cards. Once you've saved one, a Next → appears right there (and in the bottom bar).
Stage 3 · Verbs. Each right-column system now shows its icon on its card. A + shows on each card's lower edge — click it to add a verb; saved verbs sit centred (a +N opens the full list). Once you've added one, Next reveals the subsystems.
Stage 4 · Subsystems. The Immune system glows; click it to fan its four subsystems out as chips — to the right if it sits in the left column, to the left if it's on the right, above if it's the centroid. Click a subsystem and a system to thread a labelled line. Threaded ones leave the fan; click the line's label to add a reason/verb (its reason shows above the verb). Toggle Reasons or Verbs and each system's chips appear on its card — click a chip to edit & save, the + adds another, and a reason shows its first 15 characters with a + to expand. The progress bar tracks every stage.
