/* camera.css — the camera screen (js/ui/camera-screen.js).
 *
 * A black, full-screen viewfinder with the controls floating over it, like
 * the phone's own camera: everything readable in sun (white on dark, a text
 * shadow on anything over the picture), every control at least 44 px, the
 * shutter big and in reach of a thumb. Portrait puts the controls along the
 * bottom; a phone turned sideways moves them to the right edge. Everything
 * keeps clear of the notch and the home bar (safe-area insets).
 * The camera is always dark, whatever the phone's theme; sheets and dialogs
 * opened from it use the normal app colours.
