# don't have their own add_header directives.

# NOTE: nginx does NOT inherit server-level add_header into location blocks

|
# that define their own add_header (e.g. /assets/). Those blocks repeat
|
|
# the security headers explicitly to avoid the inheritance pitfall.
|

# /api/ is intentionally excluded - the FastAPI backend sets its own.
