/**
 * css/views/mobile-shell.css
 * --------------------------
 * Phone and small-tablet layout. Imported last so it can override the desktop
 * shell without touching the individual view stylesheets.
 *
 * The two goals are:
 *   1. Nothing may ever scroll sideways. Widths collapse instead of overflowing,
 *      and the rail that used to sit beside the workspace moves to the bottom so
 *      the full screen width belongs to the report.
 *   2. The shell respects the physical device: notch insets, the home indicator,
 *      and the keyboard are all accounted for, and the layout is driven by
 *      dvh + fractions rather than fixed pixel gaps so it stretches to any
 *      phone aspect ratio instead of letterboxing.
