• Priority tiers: critical jobs bypass deferral; enrichment jobs deferrable
• Scheduled throttle: spread jobs across off-peak windows
• Platform Events for fan-out reducing Queueable job count
• Request async limit increase from Salesforce with usage justification
• Architect month-end capacity: job count estimate before go-live
