/*
  GBMS site kit · the home-page parameter table as CSS variables (saas-frontend-standard 「〇·一、首页统一参数表」), plus
  the few base classes every block shares. Import once in the host (main.ts or the home page): every sdk/vue/site
  component reads these.
  🔴 The product sets only the brand colour (`--gs-brand`). Every other value, gradient ends and the dark download band
  included, is the standard's or derived from the brand here; scripts/kit-guard (saas-frontend-standard 〇·二 3) fails a
  product release that redefines one. 🔴 Layers (`--gs-z-*`, 〇·二 9) are fixed too, header < float < popover < dialog
  < dialog over a dialog < support window < toast, and every floating kit is teleported to <body>, so a host's stacking
  context can never cover it; the kits carry the same numbers as fallbacks (workbench pages may not load this file).
  Vendored byte for byte (README.md).
