/* TerrariAPI — hoja de estilos compartida (index.html y changelog.html)
   Concepto: la página es un corte del mundo. Arriba la superficie (cielo, colinas y el árbol),
   y al bajar se atraviesan capas cada vez más profundas.
   Paleta: la base sale del pixel art del logo (cielo, copa azul, colinas verdes, tronco gris y contorno negro);
   se suman tonos cálidos (sol, lava, gemas) y capas de color para el subsuelo. */
