/* =====================================================================
   Estilo base del sitio · Editor V3

   Punto de partida de todo sitio nuevo: color, tipografía y ritmo ya
   resueltos para que la primera impresión sea buena y para que la IA o
   el editor visual tengan una base sana sobre la cual construir.

   Todo cuelga de las variables de :root — cambiar la identidad del
   sitio es tocar ese bloque y nada más.

   Ojo con las fuentes: si el sitio define fuentes propias, EditorSite
   las aplica con `html body` / `html h1..h6`, que le ganan en
   especificidad a las reglas de acá. Es a propósito.
