/* ==========================================================================
   PlugSolarHub liquid-glass design system, site default.
   Loaded on every page. Pure CSS: no WebGL, no per-frame work, no layout JS.

   Two tiers:
     Tier 1 (this file)  static liquid glass. Deep-green gradient surfaces, gold
                         accents, glass edges and sheen, editorial typography.
                         Costs one cached request. Renders identically everywhere.
     Tier 2 (site.js)    the animated WebGL shader. Budget-capped to the hero
                         moments, lazy, paused offscreen. Purely additive: every
                         surface below already looks finished without it.

   Class names are canonical .psh-*, with .gr-* kept as aliases.
