+## Unreleased
+
+### Fixed
+- Docker: a clean `docker compose up --build` now reliably installs Chromium for
+  the browser tools. The Playwright browser CLI is invoked directly
+  (`node node_modules/playwright/cli.js install`) to avoid an npm bin-name
+  collision that left a from-scratch build failing with `playwright: not found`
+  (exit 127).
+- Docker on Windows (WSL2): a fresh `docker compose up --build` no longer fails
+  when `.env` is absent — `.env` is now optional. A new `.gitattributes` pins
+  shell scripts and other build-critical files to LF so a Windows checkout
+  (CRLF) builds cleanly.
+
+### Added
+- Docs: Windows/WSL quickstart notes in the README and `docs/docker.md`. The
+  browser tools run entirely inside the container (no host X server or WSLg).
