Full jitter spreads clients most evenly and is the usual default for API clients.
Always prefer the server's Retry-After (or retry_after in Telegram and Discord bodies) when present.
Only retry idempotent operations automatically, or attach an idempotency key.
Put a cap on the total time; after that, move the job to a dead-letter queue.
