Icons are plain .png, a cacheable extension by default, so the zone's
"Browser Cache TTL = 1 year" pinned them to max-age=31536000 regardless of
the 300/3600/604800 that nginx sends per class. Extend the edge rule to
/gamedata/ and keep respect_origin, so the nginx header wins and a 404
(notably no-store from the gamedata 404 handler) is never pinned.
Rebuild production nginx from the repo (deployment/proxy/*) with a single
Cache-Control owner per route: the app stays the source, nginx only manages
headers, and Cloudflare stores the public API allowlist at the edge.
- deployment/proxy: nginx.conf, mime.types, nginx-cms.conf and the
blue/green upstream snippet; config backed by scripts/nginx-sync.sh
(idempotent install + reload, --check/--force).
- nginx serves Cache-Tag headers on the public allowlist (cms-public),
gamedata, client and camera responses so the edge and purge stay in sync.
- src/lib/edge-cache.ts + tests: coalesced, fire-and-forget edge purges that
no-op unless Cloudflare is configured; scripts/cf-purge.sh and
cf-setup-cache.sh create and purge the cache rule.
- src/lib/cloudflare-api.ts: purgeCacheByTags/purgeCacheByUrls.
- Purge hooks after catalog exports (public + gamedata) and on shop, team,
guild, photo and rare-values edits; ci-deploy purges after each release.
- src/proxy.ts excludes the imaging/images docs from the middleware matcher.
