/* ==========================================================================
   FROG LOADER — barra de progreso con una ranita que salta entre nenúfares
   Concepto: la barra es la superficie del agua. Cada aterrizaje hunde un
   nenúfar y dispara ondas; al llegar al 100% una onda mayor y el desvanecido.
   Reglas del proyecto: cuadrícula de 8px · curvas suaves (nada lineal) ·
   fondo mineral oscuro con backdrop-blur · un solo acento verde.
