/* Fiber Color Code — legal site.
   Branding mirrors the app: tokens are the literal values from
   lib/core/theme.dart (FiberTokens), radii from the same file, and the type
   stack matches the app's platform default (the app sets no fontFamily, so
   it renders SF on iOS / Roboto on Android).
   No JS, no webfonts, no external requests — a privacy policy that phones
   out to a third party on load undercuts its own contents. */
