/* Farven Calc — landing del producto (calc.farven.cl).
 *
 * Antes la landing vivía en web/web/ y se servía en /web/, tomando prestados los
 * assets del build de la app (../favicon.png, ../asset/images/logo_fc.png). Ahora
 * es la raíz del sitio y tiene sus propios assets en ./assets/, así que no depende
 * del build de Flutter: la app quedó en /app/.
 *
 * El diseño y los tokens son los que ya tenía la landing (Inter, acento #2563eb,
 * tarjetas blancas sobre fondo claro), con los bloques que faltaban para contar
 * plataformas, descargas y planes.
