perplexity-rate-limits

Implement Perplexity rate limiting, backoff, and idempotency patterns. Use when handling rate limit errors, implementing retry logic, or optimizing API request throughput for Perplexity. Trigger with phrases like "perplexity rate limit", "perplexity throttling", "perplexity 429", "perplexity retry", "perplexity backoff".
