/* The tree tab's look. Classes are santa-tree-*; colours are the --santa-* tokens of public/theme.css.
   The tab is a full-screen box (its root) with one canvas filling it and a DOM overlay inside its content box, which stops above the
   bottom bar (padding-bottom: --santa-nav-space) and below the top inset (padding-top: --santa-top). The overlay itself lets
   touches through to the canvas except on its buttons and sheets. Premium, not a casino: glass panels, one gold accent, no glow
   on everything. */
