status.g1t.sh with incident management, invites that land you in the workspace, settings as pages, usage without quotas1/**
2 * The Incidents pages' wording and arithmetic: tabs and filters read from
3 * the address, chips and their tones, durations, and reading the forms.
4 * No Workers or React imports, so it is tested under Node. The status
5 * worker checks everything again.
