fernvenue/pbr-rules-collection ? reverse-engineered prompt

Build me a simple collection of custom Policy Based Routing rule files for OpenWrt that I can drop in and use on my router.

I want the rules to follow the usual OpenWrt PBR custom user file format, and it should be easy for me to edit one place and replace the outbound interface name with my own target interface. The goal is to route selected traffic through specific interfaces cleanly, without needing a complicated setup.

Keep it practical and ready to use on OpenWrt, with clear comments so I can understand what each rule is doing. If you need to check the latest OpenWrt PBR docs online, go ahead. Also make sure the files are organized in a way that makes it obvious how to copy them into my setup and customize them for my network.
