When developing a theme, changes to CSS are reloaded instantly, but twig changes trigger a page refresh.
How can we make the twig component hot reload on changes?
Drupal should be able to reload a template or SDC using AJAX.
The Refreshless module may be able to handle this in the future.

CL Server supported something similar.

Will Experience Builder change things? Components should be live previewable.
