Help for the engine module and the pages it owns.
The engine had no help page at all until 1.0.3, so /admin/help listed nothing for Strata and the
Extend page showed no Help link beside it. The storage settings form is the configure: target in
strata.info.yml and therefore the first page a new install lands on, and it was the one page in
the module with no help of any kind.
The module page carries the ordered setup steps, because nothing else in the UI states them.
Returned as a list of short sentences rather than one paragraph: Drupal.Semantics.FunctionT.Concat
forbids concatenating inside t(), and it is right to, because the extractor cannot read a
concatenated argument and the string would ship untranslatable.
forRoute(string $routeName, \Drupal\Core\Routing\RouteMatchInterface $routeMatch) : array<string,mixed>
Implements hook_help().
| string | $routeName | The current route. |
| \Drupal\Core\Routing\RouteMatchInterface | $routeMatch | The route match. |
A render array, empty for a route with no help.
