# Code style guides

Each reference is one upstream guide converted to Markdown. Load only what the task needs:

1. Pick the reference for the language or framework below.

2. Read its index (the line range in the Index column). Each entry gives the line where a section starts.

3. Read only the sections you need, starting at those lines.

Code fences tagged `good` show recommended code; fences tagged `bad` show code to avoid.

The project's own configuration, formatter, and surrounding code take precedence over these guides.
