Composites: threading

• (Idea) In-world, a composite is a thread: both thumbs stay down from one spell into the next, so the Glass never closes and the spells run together. Lifting a thumb closes the Glass. This explains why composites are drawn as one continuous stroke (section 6).
• (Idea) A thread is named by its parts in the order drawn, e.g. "Repel into Gale". Players never name or invent anything.
• (Idea) Example threads:
  • Repel into Gale: the push lands, then the wind carries the target further back.
  • Gale into Coil: the wind throws the vine, so Coil hits from range.
  • Coil into Facet Seal: a shield of thorns. The first cross-side thread most players find.
