/* ==========================================================================
   Tech Mansion Design System — 1.15.0 UI overhaul
   --------------------------------------------------------------------------
   One visual language across the whole frontend, modelled on the
   clean mockup standard the user approved: white surfaces, hairline
   borders, soft shadows, generous spacing, one accent colour used
   sparingly. This sheet loads LAST in the cascade; it re-skins the
   existing components (1.10–1.14 markup) rather than replacing them,
   so no data, SEO or behaviour changes ride along.
