+  # This works by:
+  #   1. Overriding the `GTK::Runtime#tick_core method` (example found in lowrez.rb)
+  #   2. It fetches 'https://github.com/marcheiligers/dr-input/releases/latest' which will redirect to the latest release.
+  #      DRGKT follows redirects, so we get the HTML from the final destination.
+  #   3. That HTML contains OpenGraph tags including:
+  #        `<meta property="og:url" content="/marcheiligers/dr-input/releases/tag/v0.0.25" />`
+  #      which contains the latest version number.
+  #   4. That then allows us to fetch that version from the releases using $gtk.download_stb_rb_raw
+  #   5. Finally it aliases the original `tick_core` method back, and cleans up the methods and instance variables created.
+  # State is maintained through the existence of method aliases and instance variables, which are removed on completion.
+  # Error handling ensures everything is cleaned up if there is a failure.
