   Enforso — design tokens, base type, icon font.

   Faithful CSS port of EnforsoTheme.swift (the `Enf.*` token namespace) and
   the SwiftUI .system(...) type usage across the iOS app. Enforso is a light,
   warm-neutral product: one emerald accent, near-black ink, soft 8% hairline
   strokes, generous rounding.

   This file is the single source of truth for the public web surface — the
   landing page, privacy, coming-soon and the UDID pages all build on it.
