Web helpers

These are the public helpers the web steps are built on. Your own step definitions call them on $this, the same way the shipped steps do, as Scenario styles explains. A page gives each helper of a trait or class a signature and a description, and Root context covers what WebRawContext itself adds.

HELPERS.md holds these helpers and the Drupal helpers on 1 page. It ships with the package, so an AI coding agent in your project can read it from vendor/.
