Each job inherits the global pace but can be throttled or paused individually. At Eco, jobs run one-at-a-time, staggered, on off-peak windows; at Max, they fan out concurrently. concurrency + interval per job are what Code wires into pg_cron / the job runner.
A mode is a one-click preset that re-tunes pace, concurrency, retries, and which jobs run. Crisis re-create/migrate spins a fresh stack from the latest backup and replays data at max safe speed; Cost-cut drops to off-peak Eco and pauses non-essential jobs; Rapid scale-up and Mass onboarding add worker concurrency and burst the import/intake queues while protecting the live transaction paths.
