Currently the lightbox's top and bottom app bars respond to touch by appearing and disappearing. Currently they just abruptly appear and disappear, but they should nice entrance/exit animations. The React Native app has them slide in and out; we could do that or perhaps a fading animation.
This needs to work on devices where the OS intrudes on the app's space at the top and bottom of the screen (like the iPhone "notch" for the camera etc.).
The layout should look reasonable even when the user changes their preferred text size in their device's accessibility settings.
