/* Admonere — landing
   Sistema visual: DESIGN (hubspot).md, con la paleta de Admonere en lugar del naranja.
   - Un solo color de acción: Navy #0B2D58. El dorado es un acento esporádico en bloques oscuros.
   - Serif en una sola variante (500) para títulos de 24 px o más; sans para todo lo demás.
   - Botones con radio 8, tarjetas e imágenes con radio 16. Profundidad con bordes finos, sin sombras.
   Fuentes: Newsreader (sustituto editorial de HubSpot Serif, ya elegido para la marca) e Inter
   (sustituto de HubSpot Sans y tipografía de producto). */
