/* =========================================================
   letsgodrop · base
   Sistema visual propio, sobrio y luminoso: blanco o negro de fondo, materiales de cristal
   (cabecera, pie, globos y menús translúcidos), Inter con titulares apretados, un color por fase
   y la explicación en iconos, diagramas, maquetas y gráficos antes que en texto.
   Un solo paradigma por cosa:
   - Botón azul = la acción de la pantalla. ↗ abre otra web; → avanza aquí.
   - Botón gris = lo secundario (volver, saltar, ver un tutorial).
   - Halo azul que late = lo siguiente que toca. Verde = hecho.
   - Palabra con subrayado de puntos o icono (i) = tiene definición: el mismo globo para todo.
   - Campo con candado = sale de tus datos; campo con lápiz = lo puedes cambiar.
   - Cada fase tiene su color: su icono, su tramo de la barra, sus números y sus acentos.
