The Caddy example has `encode zstd gzip`; the nginx one had nothing, so a deployment following it shipped every asset uncompressed. Measured against the built app that is 915 KB on the wire where 307 KB would do -- the difference falls entirely on first load, and silently, since nothing about it is visible without inspecting response headers. `text/javascript` is listed explicitly. The server sends scripts with that type rather than `application/javascript`, so a conventional gzip_types list compresses the stylesheet and leaves the 647 KB script alone -- which is what happened on the first attempt at this change. text/event-stream is deliberately not listed. Compressing or buffering the push stream would break it; proxy_buffering is already off below for the same reason. Verified that /api/events still delivers a StateChange event through the proxy, as plain text, while assets come back gzipped with Vary set.
