1/**
2 * g1t's artwork: thin isometric line drawings of what it does, on a faint
3 * grid, with small dots at the corners. Everything is drawn from one
4 * projection so the pieces sit together.
5 *
6 * The drawings move, and the motion explains the idea: changes stacking
7 * in the queue, a line tracing back to why it exists, a deploy reaching
8 * the edge. It is CSS only (the `art-*` classes in app.css):
9 * transforms, opacity and stroke offsets, which the GPU handles. Each
10 * drawing pauses while it is off-screen (`Live`), and under
11 * prefers-reduced-motion nothing moves and every drawing shows its
12 * finished state.
