## Summary by CodeRabbit

* **Documentation**
* Updated instructions to use the domain `affine.localhost` instead of
`dev.affine.fail`.
* Simplified setup steps by removing references to DNS service
configuration and custom DNS server entries.

* **Chores**
* Removed DNS server configuration and related files from the
development environment setup.
  * Updated example descriptions to reflect the new domain.
