Running _/bin/dev-browser fails with Playwright error: Executable doesn't exist at ~/.cache/ms-playwright/.../headless_shell. DevBrowser tool currently depends on per-user browser downloads and silently fails (existing server returned timeouts). Need to ensure DevBrowser package includes browser binaries or startup surfaces install guidance clearly.
As a stopgap, we could just set this variable in the repo's .envrc file so it gets loaded by direnv automatically.
DevBrowser initially failed due missing playwright browser and shared library resolution. Workaround used for this audit: launch with PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH=/home/ben/.nix-profile/bin/chromium. This allowed successful navigation, eval, and screenshot capture for /tasks, /news/, /files. Tooling issue remains open for proper packaging/docs.
