   Identidad: empresa olivícola real. Paleta tomada del mundo del
   olivo (hoja, aceituna, aceite, tierra) — no cream+terracota
   genérico. Tipografía serif con carácter para titulares (evoca
   etiqueta de aceite artesanal) + sans-serif limpia para el cuerpo.

   Firma visual: esquinas "hoja de olivo" (radio asimétrico, no
   redondeado uniforme) en tarjetas, botones e imágenes, + un
   divisor de línea con hojas de olivo dibujado a mano (SVG),
   reutilizado entre secciones.
