/* ============================================================
   Gnosis IQ IdentityServer — site.css
   Matches the Next.js app's design language (emerald/slate + Geist).
   No MDBootstrap. This file plus site.js are the only frontend deps.
   Provides a compatibility layer over the Bootstrap class names
   already used in the existing .cshtml files (container, row, col-*,
   btn, form-control, alert, nav, etc.) so individual pages don't
   need to be rewritten to inherit the new look.
