2 * Home, the workspace's front page: where you're needed now, what happened
3 * since you were last here, and what is running. It never depends on the
4 * calendar: what needs you has no time window, and what happened is
5 * counted over a span you choose, since your last visit by default. Every
6 * number is worked out here from what the services return, so each
7 * definition is tested on its own (home.test.ts) and written down in the
8 * Home guide (apps/docs/.../guides/home.md). Imports only types.
