Mark light mode responses as separately cacheable from dark mode responses if the upstream server supports client hints:
```caddy-d
header {
Cache-Control "max-age=3600"
Vary "Sec-CH-Prefers-Color-Scheme"
match {
header Accept-CH "*Sec-CH-Prefers-Color-Scheme*"
header Critical-CH "Sec-CH-Prefers-Color-Scheme"
}
}
reverse_proxy upstream:443
```
Prevent overly-permissive CORS headers by replacing wildcard values with a specific domain:
```caddy-d
header >Access-Control-Allow-Origin "\*" "allowed-partner.com"
