Key Settings

Setting	Value	Purpose
worker_processes	auto	Match CPU cores
worker_connections	1024	Max concurrent connections
client_max_body_size	100M	File upload limit
gzip	on	Compress responses
expires	1y	Static asset caching

Static Asset Caching

Assets with fingerprinted filenames (Vite builds) get 1-year cache headers with immutable directive. Browsers won’t revalidate these files.
