/* Destello (sparkle) único sobre el logo de Pragma.
   Aparece una sola vez al cargar la página, en el extremo superior izquierdo del logo.
   El PNG mide 900x402 y el logo visible arranca en x=61 / y=63, por eso el destello
   se ubica en 10% / 22% de la caja: justo sobre la esquina superior izquierda. */
