benecaster_get_header()

Prints the site header in a way that works on both classic and block themes. On a block theme it renders the header block template part; on a classic theme it calls get_header(); on a theme that has neither, it prints nothing and stays quiet.

That last case is the reason it exists. Calling get_header() directly from a plugin template on a block theme fills the debug log with deprecation notices, which is alarming to a podcaster who has done nothing wrong. If you are overriding templates/episode/single.php, templates/show/single.php, or templates/archive/archive.php in your theme, swap get_header() for this and the notices stop.

Its counterpart is benecaster_get_footer().
