What Twig variable can i use to view Page Title or Taxonomy Name for a Taxonomy Type page

Question

In Drupal 8 I need a way to get the Current pages title or Taxonomy name/ID.

In the template taxonomy-term.html.twig the variable works:

{{ term.id }}

I need the variable to work in page.html.twig

the following variables work only if the current page type is a node and not a taxonomy:

{{ head_title_array.title }} and {{node.field.category.entity.tid.value}}

I need to access this variable in the page template in order to use it as a class for a region based on what taxonomy page type is being displayed.

EDIT:

prints out page__taxonomy__term__# or null if not a taxonomy page:

{{ theme_hook_suggestions }}

prints out the title of the current page regardless of type:

{{ page['#title'] }}
