Proposed Solution:
From the default regions in core and the page.html.twig file suggests a page.header and page.footer region will exist and we should add them to the page.html.twig template and info file..
The page_top, page_bottom are the only other ones in there but they get easily confused with the html.html.twig variables, so opted not to include them.
Problem/Motivation: When switching from theme inheritance with a base theme of
galactus
to starterkit fork, the regions don't match well becausegalactus
defined regions aren't inherited: https://www.drupal.org/docs/theming-drupal/sub-theme-inheritanceProposed Solution: From the default regions in core and the page.html.twig file suggests a
