/* CMH Globe: every style js/globe.js needs. All classes are prefixed cmhg-.

   .cmhg-root (plus state classes) and fills it.

   Hooks the page can set on the container:
     --cmhg-canvas-z / --cmhg-labels-z  z-index of the WebGL canvas and of the label layer
                                         (lets a title sit between them, if no ancestor inside
                                         the container creates a stacking context)
