Load the "Imagery Layers" demo, expand the controls, and zoom in to a white area like Greenland or Antarctica.  The controls fade away, because you're setting the transparency too thin in hopes that your light-background claro will be placed against the blackness of space.  Instead, give this a try:

```
.claro .dijitTitlePaneContentOuter {
    background-color: rgba(255, 255, 255, 0.7);
    color: black;
    text-shadow: 0 0 5px #fff;
}
```

(Note that placing .claro on the front allows you to remove the !important qualifier).

Also, can we apply the expanding-controls trick to Imagery Adjustment and maybe to the sensor demo?
