 * The phone screen.
 *
 * Dark by default because the app is used in the same moments the glasses are — outdoors,
 * quickly, one-handed — and because the lens preview is white on black and a page that
 * frames it in white makes the preview look like a photograph of a different device.
 *
 * The controls are large. Not for style: the wearer is holding a phone in one hand while
 * talking to a stranger, and every control on this page has a version that is a tap on the
 * glasses precisely because looking down at a phone is the thing being avoided.
