Edge audit complementing doc 13 (server-side perf). Confirms cold-load
"feels slow" perception is dominated by:
- no HTTP compression at Traefik (2.74 MiB raw JS bundles per cold load)
- no Cache-Control on hashed-asset URLs (28 conditional GETs per warm load)
- first-fetch poster image transcode ~385 ms (server-side, doc 13 #02)
TLS, MTU, HTTP/2, cert chain, middleware chain, Pi-hole hairpin all
audited and clean. Pi-hole missing local DNS rewrite for arrflix.s8n.ru
(LAN clients hairpin via WAN unless /etc/hosts pin in place).
Top quick win: add `compress@file` middleware in
/opt/docker/traefik/config/dynamic.yml + reference from Jellyfin router
label. ~70 % cold-load wire-size reduction (2.74 MiB to ~0.82 MiB
gzip / ~0.69 MiB brotli). One file edit, no architectural change.
No fixes applied. No state mutated. No Traefik reload.
