/* ==========================================================================
   SPUR HOMES — Liquid Glass material system
   Optics (SVG refraction + fallback) come from assets/js/vendor/liquid-glass.js,
   which writes an inline backdrop-filter. Everything here is the *dressing*:
   tint, rim, specular highlight and shadow that make a panel read as glass.

   Because the module sets backdrop-filter inline, the CSS declaration below is
   the progressive-enhancement floor: frosted glass with no JS at all.
