/* ============================================================
   FAMTECTOR · SISTEMA DE DISEÑO COMPARTIDO
   ============================================================
   Un solo archivo de tokens + componentes reutilizables para que
   TODA la web (landing, ficha del rescatista, futuras vistas)
   comparta la misma identidad visual que la app Famtector ID.

   Cómo usarlo en una plantilla nueva:
     <link rel="stylesheet" href="/static/css/famtector-theme.css">

   Los tokens fueron tomados del landing (index.html), que ya tenía
   el sistema más completo, y se extendieron con los estados que
   faltaban (alerta / extraviado, éxito, info).
