## Description Define a shared LF line-ending rule so Git checkouts and formatting checks behave consistently on Windows, Linux and macOS. This is a repository-wide configuration task, separate from the frontend integration in PR #4. ## Tasks - [x] Add `.gitattributes` to normalize text files and check them out with LF. - [x] Add an EditorConfig LF rule that editors and Prettier can use, without conflicting with the Prettier configuration introduced in PR #4. - [x] Renormalize tracked text files and keep application behavior unchanged. - [x] Document the line-ending rule in the Norwegian README. - [x] Verify Git line endings, formatting, tests, linting and the production build. ## Done when Tracked text files use LF, a Windows checkout keeps LF even with `core.autocrlf=true`, and the frontend formatting check passes without a command-line line-ending override. Tests, linting and the production build pass.
