Provide the path to the certificate file at `certs/live/$DOMAIN/fullchain.pem`
and the private key file at `certs/live/$DOMAIN/privkey.pem` to twins.
## DisableHTTPS
### StyleSheet
Provide the path to a style sheet to serve instead of the default style sheet.
This option only applies when serving HTTPS connections.
### DisableHTTPS
Pages are also available via HTTPS on the same port by default.
Set this option to `true` to disable this feature.
Pages are converted automatically by [gmitohtml](https://code.rocketnine.space/tslocum/gmitohtml).
## StyleSheet
Specify a custom CSS stylesheet file if you want to override the default. This only
affects the `HTTPS` protocol (obviously).
### DisableSize
The size of the response body is included in the media type header by default.
