 Documentation lives in `src/content/` as Markdown/MDX. To contribute, fork the repo, make your changes on a branch, and open a pull request. For problems, [open an issue](https://github.com/lycheeverse/lycheeverse.github.io/issues/new/choose).
 
 Before opening a pull request, run `pnpm precommit` to check formatting and linting, since CI enforces both.
