Spinner, progress bar and sliders drawn as firmware text instead of images: no image send per update. First screen: a spinner and progress bar inline in the page's text area. Tap for the second: a slider in each text box of its own (swipe moves, tap edits, swipe changes, tap keeps, hold undoes). "Done" opens the third: a status line, toast, live readout and ticker in text boxes over a chart tile that changes every 5 s.
