/* ================================================================ scenery
   Wireframe mountains behind every page: one canvas drawn by js/scenery.js, mounted once by
   mountShell() after first paint. Fixed to the viewport at z-index -1 in the root stacking context,
   so it paints over the page background and under every box; never hit-testable, never in layout,
   never wider than the viewport. Opaque surfaces (header, footers, filled cards) simply cover it.
   Sized to the large viewport height so a phone's collapsing URL bar never resizes it.
   Per page: <body data-scenery="off"> removes it, data-scenery="hero" draws it a little stronger.
   data-layer="scenery" makes the layout gate check it as its own layer, like the overlays. */
