+
+# Regenerating Playwright Screenshot Expectations
+
+Automates the process of triggering the `PR: Update Playwright Expectations`
+GitHub Action by creating a labeled PR from `origin/main`.
+
+## Steps
+
+1. **Fetch latest main**
+
+   ```bash
+   git fetch origin main
+   ```
+
+2. **Create a timestamped branch** from `origin/main`
+
+   Format: `regen-screenshots/YYYY-MM-DDTHH` (hour resolution, local time)
+
+   ```bash
+   git checkout -b regen-screenshots/<datetime> origin/main
+   ```
+
+3. **Create an empty commit**
+
+   ```bash
+   git commit --allow-empty -m "test: regenerate screenshot expectations"
+   ```
+
+4. **Push the branch**
+
+   ```bash
+   git push origin regen-screenshots/<datetime>
+   ```
+
+5. **Generate a poem** about regenerating screenshots. Be creative — a
+   new, unique poem every time. Short (4–8 lines). Can be funny, wistful,
+   epic, haiku-style, limerick, sonnet fragment — vary the form.
+
+6. **Create the PR** with the poem as the body (no label yet).
+
+   Write the poem to a temp file and use `--body-file`:
+
+   ```bash
+   # Write poem to temp file
+   # Create PR:
+   gh pr create \
+     --base main \
+     --head regen-screenshots/<datetime> \
+     --title "test: regenerate screenshot expectations" \
+     --body-file <temp-file>
+   ```
+
+7. **Add the label** as a separate step to trigger the GitHub Action.
+
+   The `labeled` event only fires when a label is added after PR
+   creation, not when applied during creation via `--label`.
+
+   Use the GitHub API directly (`gh pr edit --add-label` fails due to
+   deprecated Projects Classic GraphQL errors):
+
+   ```bash
+   gh api repos/{owner}/{repo}/issues/<pr-number>/labels \
+     -f "labels[]=New Browser Test Expectations" --method POST
+   ```
+
+8. **Report the result** to the user:
+   - PR URL
+   - Branch name
+   - Note that the GitHub Action will run automatically and commit
+     updated screenshots to the branch.
+
+## Notes
+
+- The `New Browser Test Expectations` label triggers the
+  `pr-update-playwright-expectations.yaml` workflow.
+- The workflow runs Playwright with `--update-snapshots`, commits results
+  back to the PR branch, then removes the label.
+- This is fire-and-forget — no need to wait for or monitor the Action.
+- Always return to the original branch/worktree state after pushing.
