/* ============================================================
   Synch — public landing page (Views/Home/Landing.cshtml)

   Loaded only by the landing view through _LayoutFrontend's Head
   section, the same way MatchingPage.cshtml loads synch.css. The
   admin bundle is never loaded here, so this file is self-contained:
   it declares its own Poppins faces (same self-hosted files the
   admin uses) and carries hex copies of the brand tokens from
   wwwroot/Content/site/overrides/tokens.css.

   Visual language: the auth pages' door — indigo canvas, white-ink
   lockup — extended to a full page. The brand gradient is spent
   exactly once, on the "thread" that joins the two hero sentences;
   every action stays solid brand blue like the rest of the product.
   ============================================================ */
