ABC CUSTOM SUBTHEME EXAMPLE
=================================

For update-safe Twig/module-template overrides, create a separate custom
subtheme outside the contributed ABC directory, for example:

  /themes/custom/abc_custom/

Copy the two *.example files from this directory there, remove the .example
suffixes, create css/custom.css and a templates/ directory, then enable the
subtheme. Any Twig overrides placed in that subtheme survive ABC updates.

Do not place site-specific Twig overrides inside /themes/contrib/abc.
