/* ==========================================================================
   Calculadora de pace — landing limpia, un solo acento
   ==========================================================================
   Filosofía:
   - Header product-style coherente con Dashboard/Zapatillas/Actividades
     (left-aligned h3 rojo). El form vive en una card limpia.
   - 1 acento (rojo de marca) reservado para CTA "Calcular" y el valor
     numérico de los resultados.
   - Más cálculos (Progresión / Calorías) en tabs, mismo patrón que la
     home FAQ.
