/**
 * Queue-health threshold configuration domain: per-project age buckets for the
 * Factory Overview queue-health chart.
 *
 * Stored per `(org, github_project)` — each connected GitHub project gets its
 * own age thresholds so a fast-moving automated pipeline and a slow human one
 * can bucket "how old is the work" differently. `thresholdsSeconds` is an
 * ordered-ascending list of age boundaries in seconds: an item younger than
 * the first boundary is green, younger than the second amber, younger than the
 * third orange, and red otherwise. Seconds (not hours) so sub-minute buckets
 * are representable for fast automated flows.
