Wildcard for 3rd level domains

Hi! Here is what I got

Current Setup

Rails application with implemented user subdomain functionality
Kamal 2 deployment with Thruster reverse proxy
DNS records configured for wildcard domain
Current deploy.yml configuration:
```
proxy: 
ssl: true
host: mysite.com
```

Goal Enable support for user-specific subdomains in the format:

name.mysite.com
another_name.mysite.com

What is the correct approach to handle wildcard subdomains with Kamal/Thruster?

Option 1: Remove host from deploy.yml completely (concerns about SSL certificate compatibility) Option 2: Use wildcard notation '*.mysite.com' Option 3: There is no such possibility, go back to nginx/traefik and suffer.

Kamal version: 2.2.2 Rails version: 8.0.0.beta1 Thruster version: 0.1.8
