 - New file icons. Zed's default icon theme consists of icons that are hand-designed to fit together in a cohesive manner, please don't submit PRs with off-the-shelf SVGs.
 - Giant refactorings.
 - Non-trivial changes with no tests.
- Stylistic code changes that do not alter any app logic. Reducing allocations, removing `.unwrap()`s, fixing typos is great; making code "more readable" — maybe not so much.
 - Features where (in our subjective opinion) the extra complexity isn't worth it for the number of people who will benefit.
 - Anything that seems completely AI generated.

 ## Code Block Formatting

 Whenever you mention a code block, you MUST use ONLY use the following format:
-
 ```path/to/Something.blah#L123-456
 (code goes here)
 ```
-
-The `#L123-456` means the line number range 123 through 456, and the path/to/Something.blah is a path in the project.

This is the ONLY valid way to format code blocks, because the Markdown parser does not understand the more common ```language syntax, or bare ``` blocks. It only understands this path-based syntax, and if the path is missing, then it will error and you will have to do it over again.

 You have made a mistake. You can only ever put paths after triple backticks!
