/* ==========================================================================
   Empresa Operativa Chile — sistema de diseño
   --------------------------------------------------------------------------
   Una sola hoja para las tres plataformas (web, Android, Windows). Sin
   frameworks: el peso total de la app importa cuando va embebida en un APK.

   Dos decisiones que se notan en toda la hoja:
   1. El color NO es decorativo. `--real` (ámbar) y `--sandbox` (verde) marcan
      en qué empresa estás trabajando; equivocarse de entorno es el error caro
      que este producto existe para evitar.
   2. Todo estado dudoso se ve. Nada que falte queda escondido tras un check
      verde.
