 ## Additional Enhancements
-### Integrate Hiro Rate Limit Headers
+### Integrate Hiro Rate Limit Headers - Completed
 - Update StacksApiService to parse response headers (e.g., x-ratelimit-remaining-stacks-minute, ratelimit-remaining) after API calls.
 - Use headers to dynamically adjust TokenBucket (e.g., sync available tokens with remaining counts, respect retry-after).
 - Log header info for monitoring.

 ## Tasks
-- Add HIRO_API_KEYS as a secret in wrangler.toml (e.g., "key1,key2,key3,key4,key5").
-- After implementation, build and deploy to staging.
-- Run tests: Simulate bursts with Postman/scripts; verify with staging frontend.
