# QNBS-v3: nginx only inherits a parent level's add_header directives when the current level has
# NONE of its own — a location block that sets even one add_header (e.g. Cache-Control below) drops
# every server-level add_header for requests matching it. Both asset-caching location blocks below
# therefore duplicate the security header lines explicitly rather than relying on inheritance.
