   Liquid Glass Design — tokens + components (v2.1)
   Drop-in CSS. Pair with liquid-glass.js for real refraction on Chromium.
   v2.1: every text token passes WCAG AA (4.5:1) on #fff, #f5f5f7 and #1c1c1e;
   separate tint for text vs button fill; semantic colours; B2B components
   (proof row, pricing, KPI, alerts, responsive table-to-cards).
