/* Design system Timaná — generador DIAN
   Se amplía el ancho máximo respecto a las apps de postcosecha porque esta es una
   herramienta de escritorio con tablas de muchas columnas: 680px haría ilegible la
   grilla de 13 campos.

   PENDIENTE — deriva respecto a postcosecha/assets/tokens.css: coinciden los tokens
   de marca y superficie (--turquoise, --deep-green, --bg, --surface) pero difieren
   nombre y/o valor en el resto:
     --muted  #6B7A80  vs  --text3         #5C7068
     --border #E2DDD6  vs  --border        #D4E8E4
     --text   #1F2A2E  vs  --text          #1F1F1F
     --error  #C0392B  vs  --red           #F15A62
     --warn   #B8860B  vs  --yellow        #E8A020
     --ok     #2E7D5B  vs  --green-success #2E7D32
     --radius 8px      vs  --r             8px
   Unificar contra tokens.css cambia el aspecto de una UI ya probada, así que queda
   como decisión aparte. Ver dian-api/README.md. */
