/* ==========================================================================
   SURU (página de Joaquín, "TrueFrame", adaptada)
   Paleta: azules (navy, cobalto, cian, celestes)

   [SURU] Qué cambió respecto al CSS de Joaquín (todo marcado con "SURU:"):
     1. Los colores de marca ahora son los del logo nuevo (#04336B, #0351A6, #0970CF, #2AADFC).
        Se conservaron los nombres de los tokens para no tocar el resto.
     2. Se quitó lo que ya no existe: la lista "Your images" (.queue, .file-item, .file-result)
        y la píldora "Likely AI / Likely real" (.verdict), porque ahora se muestra un puntaje.
     3. Se agregó lo nuevo: login, chat, resultado, mapas de calor, JSON, diálogos.
   Lo demás (base, hero, zona de carga con esquinas, botones, miniaturas, pie) es el de Joaquín.
