   TrámiteSimple — sistema visual «expediente»
   -----------------------------------------------------------------
   Mobile first real: el layout se diseña para 375–430 px y recién
   después se adapta a desktop (spec V2 §3).

   Dirección: institucional / administrativa. Una sola familia sans
   para títulos y texto, esquinas rectas y filetes en lugar de tarjetas
   redondeadas. Azul marino como color de marca y un azul claro como
   acento, sobre fondo gris frío. Transmite seriedad y oficialidad sin
   imitar portales estatales (spec V2 §27/§49): sin escudos, sin el
   celeste de Argentina.gob.ar ni su estructura de página.

   Regla de composición: el formulario es una hoja blanca apoyada sobre
   una banda azul marino; el resto del sitio es claro. El azul claro
   solo va en detalles (filetes, kickers, numerales sobre la banda),
   nunca en botones ni en texto largo.
