ansible/ansible-examples ? reverse-engineered prompt

Build me a simple set of Ansible example playbooks that show how to set up a few common server apps and use best practices along the way. I want this to feel like a starter repo people can copy and learn from, with clear examples for things like a basic LAMP setup, WordPress, Tomcat, MongoDB, Windows, and a couple of more specialized cases. Keep each example easy to follow, with a short README style explanation of what it does and how to run it. Make the examples work together where that makes sense, and include at least one example that shows off more advanced Ansible features, not just basic install steps. If you need to look up current docs online, go ahead. The goal is for someone new to Ansible to open the repo and immediately understand how to use the playbooks and adapt them for their own servers.
