/* ==========================================================================
   Solar Saver Zambia — Redesign (v3)
   --------------------------------------------------------------------------
   A premium, glass-and-bento redesign that keeps the SolarSaver Group brand
   palette (Navy #22384D · Slate #49637C · Steel #5C7691 · Solar Gold #FFD200)
   and applies a modern, technical, spacious visual language:
     · Floating frosted-glass navigation bar
     · Large rounded surfaces + bento-grid compositions
     · Clean typography with clamp()-based fluid scale
     · Restrained, accessible motion (prefers-reduced-motion honoured)
   Single themeable stylesheet. Dark is the brand's native navy field and the
   showcase default preference; light remains fully supported via the toggle.
