   The layout above is desktop-first. Three things have to change on a phone,

     * The 146px nav rail has nowhere to go, so it lies down along the bottom
       instead - same markup, other axis, thumb-height.
     * iOS Safari zooms the whole page whenever a focused control is smaller
       than 16px, and the operator cannot undo it. Every control is lifted to
       16px rather than trying to suppress the zoom.
     * A dialog centred in the viewport is a stretch away from the thumb, so
       dialogs meet the bottom edge as sheets.                                */
