Prettier config for consistent formatting

Formatting consistency matters, but humans shouldn’t be the ones enforcing it in code review. Prettier makes diffs smaller and reviews more focused on logic. I keep the config minimal and aligned with team expectations (singleQuote, trailing commas, ~100 char line width). I integrate it into editors and CI so it’s painless. The key is not using Prettier as a proxy for architecture discussions—formatting is purely mechanical. Once it’s running, you can stop arguing about commas and focus on shipping.
