1/**
2 * Spend threaded to the work it produced (lib/signals.ts spendFlow): the
3 * quarter's milestones, the chosen one's work items, the chosen work
4 * item's change set in each project, and that change set's pull requests.
5 * Each box is sized by what the agents' usage on it came to (by its pull
6 * requests when usage is not known) and shaded by how much of it was an
7 * agent's. Choosing a box opens what is under it; on a phone the columns
8 * stack.
