name: WordPress Playground Tests

# Re-enabled with @wp-playground/cli v3.0.22 which has improved CI stability.
# Tests use continue-on-error: true so they won't block PRs if flaky.
#
# To run locally:
#   npm run playground:start
#   npm run playground:start:multisite

on:
  # Only run on push to main (not feature branches) to avoid duplicate runs.
  # Feature branches get CI via pull_request trigger.
