+--- g:health  This global variable controls the behavior and appearance of the
+---           `health` floating window. It should be a dictionary containing the
+---           following optional keys:
+---           - `style`: string? Determines the display style of the `health` window.
+---                             Set to `'float'` to enable a floating window. Other
+---                             styles are not currently supported.
