New post on reqwest HTTP/2 window tuning and request hedging (Dean & Barroso's "The Tail at Scale" applied to DNS forwarding). Covers DoH forwarding p99 improvement and cold recursive resolution from 2.3s to 538ms. Also adds blog build infrastructure: index generation script, draft preview server, hero metrics/before-after CSS, and normalizes date format across existing posts.
