 Adding a template for another app means dropping a `.tpl` in `default/themed/`

+A template may reference `{{ key }}` for any resolved palette key, plus three

+`fastfetch.jsonc` is linked to `~/.config/fastfetch/config.jsonc`. It draws
+`~/.config/blob/branding/about.txt` as the logo, with 2 columns of padding to

+`blob-launch-about` measures the About window against, so replacing the logo
+resizes the window to fit it. Title and keys take the theme's accent.

+A config of your own at that path is a regular file rather than the symlink, and
