Just lost several hours of my life to silly CORS issues while setting up https://static-s.umeyashiki.org as my Akkoma media base URL

Nginx "gotcha": header inheritance.

If you put an `add_header` directive inside a location block, it completely suppresses all `add_header` directives defined in the parent server block.

```
server {
add_header "X-Hdr-A" "Value";
add_header "X-Hdr-B" "Value";

location / {
add_header "X-Hdr-C" "Value"; # <-- This wipes out A and B!
access_log /var/log/a.log;
}

location /bb {
access_log /var/log/b.log; # <-- A and B will show up here just fine.
}
}
```
If your global headers are mysteriously disappearing on certain paths, maybe check your location blocks.
