Default branch: !`git symbolic-ref refs/remotes/origin/HEAD --short 2>/dev/null | sed 's|.*/||' || echo main` Report only what changed. Locate; don't fix. If no URL in `$ARGUMENTS`, ask for one.

Tell the user first: _"Running in diff mode — stashing your changes to capture a baseline, then restoring. Your working tree will be fully restored."_ If `git stash push` fails, warn and exit. ```bash git stash push -u -m "accesslint-diff-baseline" npx -y @accesslint/cli@latest "<url>" --port "$PORT" --snapshot accesslint-diff --snapshot-dir /tmp --update-snapshot git stash pop && sleep 2 npx -y @accesslint/cli@latest "<url>" --port "$PORT" --snapshot accesslint-diff --snapshot-dir /tmp --format json ``` **Branch mode** (`--branch <name>`).
