+// imagen (la lupa) marca la region que se esta mirando, y un panel
+// aparte a la derecha muestra esa misma region ampliada -- sin recortar
+// nada de la pantalla ni pedirle al usuario que haga scroll para verlo
+// completo (a diferencia de un primer intento que escalaba la imagen
+// in-place con transform, donde para ver el borde superior había que
+// mover el cursor fuera del viewport visible). Solo mouse (mousemove no

-// El overlay de hover usa background-image (no transform:scale sobre el
-// <Image object-cover>) a proposito: escalar la imagen ya recortada por
-// object-cover nunca iba a revelar las partes recortadas (ej. la cabeza
-// de una figura de accion en una foto vertical) -- el recorte pasa antes
-// del zoom, en el propio render. Con background-size en un solo valor
-// (ancho%, alto en "auto") se preserva el aspect ratio real de la foto
-// completa, y background-position 0%-100% permite recorrer TODA la
-// imagen con el cursor, no solo la porcion que object-cover dejaba
-// visible en reposo.
