/* ============================================================
   ESPIRAL 60 — SISTEMA DE DISEÑO

   PALETA (por qué encaja con el nicho):
   El nicho es apego ansioso en pareja: el usuario vive alternando
   entre la "espiral" (activación, alarma, noche mental) y la
   "calma" (regulación, seguridad, respiración). En vez de un solo
   tono emocional, la página alterna DOS fondos que narran esa
   transformación en cada scroll: navy profundo (la espiral, el
   momento de crisis) y hueso-salvia claro (la calma después de
   regularse). El coral cálido es la única nota de urgencia/acción
   (CTAs), y el verde salvia es el color de "estás a salvo".

     --color-ink        #131B2E  → navy casi negro, "la espiral"
     --color-ink-soft   #1E2A47  → navy para tarjetas sobre fondo oscuro
     --color-mist       #F4F3EF  → hueso claro, "la calma"
     --color-mist-card  #FFFFFF  → blanco puro, tarjetas sobre claro
     --color-sage       #6E9683  → salvia, regulación / zona segura
     --color-sage-soft  #D9E6DE  → salvia claro, fondos "zona segura"
     --color-coral      #E5583F  → coral cálido, único color de acción/CTA
     --color-coral-dark #C43F29  → coral oscuro, hover de botones
     --color-text-muted #5B6478  → gris-navy para texto secundario

   TIPOGRAFÍA:
     Display  → "Fraunces" (serif con carácter, ópticas variables:
                transmite calidez humana, no corporativa — la voz de
                "amiga que ya vivió lo mismo")
     Cuerpo   → "Inter" (alta legibilidad en párrafos cortos)
     Utilidad → "IBM Plex Mono" (cifras, contador de 60 segundos,
                el "Protocolo" — da sensación clínica/replicable
                a los números clave sin perder calidez del resto)

   PATRÓN SVG:
     Anillos concéntricos tipo "ondas/espiral" — metáfora directa del
     nombre del producto y del mecanismo (interrumpir la espiral /
     respirar en círculos). Se usa en tono navy sobre el hero y el
     CTA final (la espiral), y en tono salvia sobre la sección de
     garantía (la calma, zona segura).
