/* FONY liquid glass theme (body.glass, which also carries body.dark so the
 * light-on-dark icons and text colours keep working).
 *
 * Scene: a slowly drifting colour field (#glassBackdrop, built in js/theme.js).
 * Glass: translucent surfaces that blur + saturate what is behind them, bend it
 * near the edges (SVG displacement filter, Chromium only; other browsers get
 * the blur), and are lit with a specular rim and a soft cursor-following light.
 *
 * Backdrop-filter does not nest (a glass parent hides the scene from its glass
 * children), so the two panels are plain translucent cards and the glass
 * objects (screen, buttons, console, list) sit inside them.
