/* The wind canvas.
   Shared by the pages that carry the wind engine. A gust is a property of the
   room rather than of the tree: it is released anywhere and crosses on its
   own. The canvas takes no pointer events and sits above the page but below
   the language menu and the skip link. Its strokes are thin and translucent,
   so the words under a passing line stay legible. A page that scopes its wind
   to its opening (`data-wind-scope="air"`) positions this canvas itself. */
