Is there a Code Style Guide

I'm working on a PR for KeePassDX, and I auto-format code (because I don't trust myself to keep standard formatting), but I've noticed my formatter changing a line or two that I didn't write. Before I send a PR with a few formatting clean ups, I wanted to know if there's a specific set of formatting rules I should be applying.

The issue mentions KeePassDX's formatter and formatting rules but names no files, tests, or entry points. Start by checking the repository's existing contributor guidance and formatter configuration; the work is done when the applicable style rules are identified and clearly documented or the question is answered.
