   Biopsias Mérida — Design tokens
   Paleta tomada del logo (BM):
   --teal:      #2E86AB  (azul del logo)
   --magenta:   #9C2BB9  (púrpura/magenta del logo)
   --lavender:  #9B96C7  (lavanda de los rombos)
   --ink:       #1E2036  (texto principal, casi negro azulado)
   --paper:     #FAF9FC  (fondo cálido, casi blanco)
   Tipografía: Fraunces (display) + Manrope (texto/UI)
   Motivo de firma: el "sonar" de rombos del logo, reinterpretado
   como anillo de eco (ping) que se repite como separador de sección
   y como animación sutil en el hero.
