The skill graph,
four ways.

Each skill, a named star. Each tradition, a constellation written across a winter sky. Drag the heavens; tap to learn the star.

Skills as specimens. Tier as growth. Channels as the colors a plant chose to wear. Vines connect what comes before to what comes after.

Concentric rings, one for each tier of the work. Petals split by channel. Two traditions can sit one over the other and the geometry holds.

Roots at the bottom (the entry tier), canopy at the top (mastery). Branches grow upward between what comes before and what comes after.
