/* The walk through the garden.
 *
 * With the 3D garden (html.garden-3d): the garden fills the screen behind the
 * page, and the page is mostly empty space whose scrolling walks the path.
 * Each painting's label scrolls in as you reach its easel.
 *
 * Without it (html.garden-static: reduced motion, no WebGL, or too slow to
 * load): the same page reads as a simple gallery, one painting after another.
