0.2.6-dev: the maintainer's decisions of 2026-10-12 — the 玩法说明 pages' WebP copies are lossy at quality 90 (25.6 MB of PNG → 4.2 MB; lossless stays a GUIDE_WEBP_MODE away) and /healthz?traffic=1 answers the counters to a loopback or private-network client only (a public visitor, also one a local tunnel or proxy forwards, gets the plain report; TRUST_PROXY applies as for the WebSocket limits); golden: unchanged
