- ResponseCache: Redis-backed HTTP response caching for public GET endpoints with configurable TTLs per endpoint prefix (tracks 15m, search 5m, etc.) - CacheHeaders: CDN-optimized Cache-Control headers per asset type (static 1yr immutable, audio 7d, HLS 60s, images 30d, API no-cache) - Integrated both middlewares into the router middleware stack - Unit tests for cache key generation, header rules, and config Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
